The two testcases I found in those threads (attached) both WJFFM under

Thanks for giving that a try, Dave.

I restored 1.5.25-7 and confirmed that test_wait4 succeeds standalone.
Note that the test_wait4 test fails when run with:
   python >& testall.out
Note that it does make a difference if output is redirected.
If you type:
then it hangs at the point of testing threads:
   *** Changing thread stack size ***
   caught expected ValueError setting stack_size(4096)
   successfully set stack_size(262144)
   successfully set stack_size(1048576)
   successfully set stack_size(0)
   trying stack_size = 262144
   creating task 1

Note the message from the test output that "verbose mode"
can influence the results:
 CAUTION:  stdout isn't compared in verbose mode:
 a test that passes in verbose mode may fail without it.

I would be curious if you also can reproduce this behavior.

Would someone mind trying the following to see if you get the same behavior? cd /usr/lib/python2.5/test python Observe that it hangs at "creating task 1".

And (using bash):
cd /usr/lib/python2.5/test
python >& testall.out
and observe that test_wait4 fails.


Thanks - Jim
