[Stackless] Stackless and tracing (for debugger)

[Kristján V. Jónsson]

Maybe I should chip in here and explain how we made the profile module work with stackless.
We added the "context" token in the stackless python core, so that sys.profile hook gets that token, along with the two tasklet objects being switched between, when such a context switch occurs.  We then sublcassed the profile.Profile class to deal properly with timing in different tasklets.  I can make the relevant changes to stackless availible if anyone is interested, along with the
class slprofile.Profile(profile.Profile)

The problem with that is that debuggers are not prepared for the stackless magic and just screw up. So we thought it is saner to do it per-tasklet.
