[pypy-issue] [issue1320] stm-thread-2: assertion failed when starting huge amount of threads

[Remi]

New submission from Remi <remi.meier at gmail.com>:

Here is the small example:
------------------------------
from threading import Thread
def parallel():
    t1 = Thread(target=parallel)
    t2 = Thread(target=parallel)
    t1.start()
    t2.start()
    t1.join()
    t2.join()
parallel()
------------------------------
Output after ~500 threads started:
pypy-stm: /home/remi/programming/pypy/pypy/translator/stm/src_stm/et.c:375: 
AbortTransaction: Assertion `!is_inevitable(d)' failed.
Aborted (core dumped)
------------------------------
The problem seems to come from starting thread 1 and 2 at the same time. If we 
only start 1 thread, the program happily runs out of memory with >1000 threads.
