Comment (by bgamari):

 Here is a fairly minimal testcase which reproduces the issue. Phyx-, can
 you verify that this doesn't crash in your working environment?
 {{{#!hs
 #!/usr/bin/python

 import sys
 import subprocess
 import os
 import os.path
 import time
 import shutil

 d = 'testdir'
 f = d + '/test.exe'
 log = d + '/log'
 if os.path.exists(d):
     shutil.rmtree(d)

 while True:
     os.makedirs(d)
     shutil.copy('test.exe', f)
     subprocess.check_call(f, stdout=open(log, 'w'))
     time.sleep(0.04)
     shutil.rmtree(d)
     print '.',
     sys.stdout.flush()
 }}}
