[pypy-dev] interrupts, preemption, threads

[Daniel Farina]

Hello list,

I wasn't able to locate any of the keywords ['interrupt',
'preemption', 'thread'] in the web documentation, so I come to
the list to ask what is roughly the status of these things in the
generated PyPy virtual machines on whatever applicable platforms.

What I am not asking about is PyPy's Python implemention of
threads, but rather support for those writing their own
interpreters.

Example scenarios:

- timeouts on arbitrary code fragments (conflated by the fact
that non-terminating interrupt-disabling code will allow code to
ignore the timeout, but I digress)

- writing a preemptive scheduler of closures

- making use of two processors 

- triggering garbage collections
