I'd like to have your opinion on this bug. Personally, I'd prefer to keep test_no_leaking as it is, but if you think otherwise...
One thing that actually can motivate that test_subprocess takes 20% of the overall time is that this test is a good generic Python stress test - this test might catch some other startup race condition, for example.
Regards, Åstrand

Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Michael Hudson (mwh) Assigned to: Peter Åstrand (astrand) Summary: test_subprocess is far too slow
Initial Comment: test_subprocess takes multiple minutes. I'm pretty sure it's "test_no_leaking". It should either be sped up or only tested when some -u argument is passed to regrtest.

Bog standard linux pc -- p3 933, 384 megs of ram.
"$ time ./python ../Lib/test/regrtest.py test_subprocess" reports 2 minutes 7. This is a debug build, a release build might be quicker. A run of the entire test suite takes a hair over nine minutes, so 20-odd % of the time seems to be test_subprocess.
It also takes ages on my old-ish ibook (600 Mhz G3, also 384 megs of ram), but that's at home and I can't time it.

Tell me a bit about your type of OS and hardware. On my machine (P4 2.66 GHz with Linux), the test takes 28 seconds.
