list_out : many events requests

+A. While (list_in !empty or list_out !empty)
1. If list_in is empty (need a seek)
1.1 Add requests to list_in
1.1.1 Find all time requests with lowest start time in list_out (ltime)
1.3.2 call before chunk
1.3.3 events hooks added
2. Else, list_in is not empty, we continue a read
+ 2.0 For each req of list_in
+ - Call before chunk
+ - events hooks added
2.1 For each req of list_out
- if req.start time == current context time
or req.start position == current position
- req.num -= count
- if req.num == 0
or
- current context time > req.end time
+ current context time >= req.end time
or
req.end pos == current pos
or
req.stop_flag == TRUE
- Call end request for req
- remove req from list_in
+ If GTK Event pending : break A loop
B. When interrupted between chunks
1. for each request in list_in
1.2. Remove start time
1.3. Move from list_in to list_out
+C. Unlock the traces

+Hook Adder and Hook remover
+
+Hook functions that takes a trace context as call data. They simply
+add / remove the computation related hooks from the trace context.

Modify Traceset
Points to the global traces. Main window must open a new one only when no
notify_out : queue of notifications that comes along with next processing.
+0.1 Lock traces
+0.2 Sync tracefiles
+
1. Before processing
- if list_in is empty
- Add all requests in list_out to list_in, empty list_out
- for each request in list_in
- set hooks'in_progress flag to TRUE
+ - call before request hook
- seek trace to start
- Move all notifications from notify_out to notify_in.
- for each request in list_in
- Call before chunk hooks for list_in
- - add hooks to context
+ - add hooks to context *note only one hook of each type added.
2. call process traceset middle for a chunk
(assert list_in is not empty! : should not even be called in that case)
3.1 call after_chunk hooks for list_in
- for each request in list_in
- Call after chunk hooks for list_in
- - remove hooks from context
+ - remove hooks from context *note : only one hook of each type
3.2 for each notify_in
- if current time >= notify time, call notify and remove from notify_in
- if current position >= notify position, call notify and remove from
- for each request in list_in
- set hooks'in_progress flag to FALSE
- set hooks'ready flag to TRUE
+ - call after request hook
- remove request
- for each notifications in notify_in
- call notify and remove from notify_in
- - return FALSE (scheduler stopped)
+ - reset the context
+ - if list_out is empty
+ return FALSE (scheduler stopped)
+ - else
+ return TRUE (scheduler still registered)
3.4 else
- return TRUE (scheduler still registered)
