Summary: popen2.Popen3 and popen2.Popen4 leaks filedescriptors
Initial Comment:
The code below (from Lib/popen2.py) appears to leak no
less then 4 filedescriptors if os.fork() raises an
exception (say "OSError: [Errno 12] Not enough space"
on a Solaris box running out of swap).
Popen3.__init__() appears to leak 6 filedescriptors.
class Popen4(Popen3):
def __init__(self, cmd, bufsize=-1):
p2cread, p2cwrite = os.pipe()
c2pread, c2pwrite = os.pipe()
self.pid = os.fork()
