With Python 2.2 as installed on Redhat Linux 7.3, I get
the following error with pty.spawn.

----------- test-pty.py ------------

#!/usr/bin/python2

import os, sys, pty

sp = raw_input("Spawn a new process?")
if sp == 'y':
    pty.spawn(('/bin/ls', '/etc'))

a = raw_input()
print a

------------ end code ---------------

Traceback (most recent call last):
  File "test-pty.py", line 7, in ?
    pty.spawn(('/bin/ls', '/etc'))
  File "/usr/lib/python2.2/pty.py", line 160, in spawn
    _copy(master_fd, master_read, stdin_read)
  File "/usr/lib/python2.2/pty.py", line 144, in _copy
    data = master_read(master_fd)
  File "/usr/lib/python2.2/pty.py", line 133, in _read
    return os.read(fd, 1024)
OSError: [Errno 5] Input/output error

I have checked the CVS version, and it looks like it
will still give the same error.

I am about to submit a 1 line patch, which as far as I
can tell fixes the problem (at least for me). See the
patches tracker.
