[Python-Dev] 2.3.3: test_import wreaks havoc when it runs out of memory

[Jack Jansen]

During testing 2.3.3 for MacOS9 I think I came across a bug somewhere 
in import,
but I don't have the time to track it down (and there's a workaround), 
and
it's probably only ever going to happen on OS9.
Should I put it in the bugs database anyway?

If test_import runs out of memory (probably in the 
test_module_with_large_stack
test) it fails with a MemoryError (as it should). However, from that 
point on
there is something fishy in the state of the interpreter: any later 
test that
should simply fail with an ImportError gets a SystemError: NULL return 
without
exception in stead. After a couple of these the interpreter either hangs
completely or crashes (I think around the threading tests, but I'm not 
sure).

Note that it's not a question of simply all memory being tied up: it 
seems
test_import does release most of the memory used, and many tests also 
pass
after test_import.
