Comment (by thomie):

 Usage of `ignore_errors=True` was sloppy program, sorry about that.

 It would be better to revert back to the original (working and commented)
 code:
 {{{
 def clean_full_path(name):
         try:
             # Remove files...
             os.remove(name)
         except OSError as e1:
             try:
                 # ... and empty directories
                 os.rmdir(name)
             except OSError as e2:
                 # We don't want to fail here, but we do want to know
                 # what went wrong, so print out the exceptions.
                 # ENOENT isn't a problem, though, as we clean files
                 # that don't necessarily exist.
                 if e1.errno != errno.ENOENT:
                     print(e1)
                 if e2.errno != errno.ENOENT:
                     print(e2)
 }}}


 On the real bug: you could try to eliminate any possible problems with
 `timeout`:
 {{{
 -     r = subprocess.call([timeout_prog, timeout, cmd],
 +     r = subprocess.call(['sh', '-c', cmd],
 }}}

 On Windows the testsuite uses a `timeout` program written in Haskell, on
 all other platforms `timeout` is written in Python. I'm not quite sure why
 two separate versions exist, but all the code is in `testsuite/timeout`.

 Fwiw: I couldn't reproduce this issue myself, last time I tried.
