Well, I don't have the problem, since I don't to free
scheduling, yet, maybe?
On the context switching problem:
There is a scheduler_callback interface which gets called
on every schedule() call, if set.
This could be used to switch the profiler context, maybe
using a dict to lookup the apropriate tasklet/context
But I'm not convinced that it makes so much sense. The profiler
is profiling function calls, not tasklets.
