This tracing scheme plans to use a direct function call to tracing into buffers
mapped in user-space. This should be an order of magnitude faster than the
current Dtrace implementation (c.f.

perform both dynamic and static user-space tracing. Performance comparison of
a function call vs the int3 approach is available at
