"""

|
Create and delete FILES_PER_THREAD temp files (via tempfile.TemporaryFile)
|
|
in each of NUM_THREADS threads, recording the number of successes and
|
|
failures. A failure is a bug in tempfile, and may be due to:
|
|
|
|
+ Trying to create more than one tempfile with the same name.
|
|
+ Trying to delete a tempfile that doesn't still exist.
|
|
+ Something we've never seen before.
|
|
|
|
By default, NUM_THREADS == 20 and FILES_PER_THREAD == 50. This is enough to
|
|
create about 150 failures per run under Win98SE in 2.0, and runs pretty
|
|
quickly. Guido reports needing to boost FILES_PER_THREAD to 500 before
|
|
provoking a 2.0 failure under Linux.
