On Solaris, calls to select.select() and
socket.socket() in telnetlib (and possibly others)
often fail due to unhandled EINTR signals from the OS
while select() is polling.

I think this problem is Solaris-specific since Solaris
has interruptible non-restartable sytem calls.

This behavior is apparently a known issue with the
system API select(); see
  man -s3c select
and
http://lists.community.tummy.com/pipermail/frpythoneers/2000-August/000122.html

The recommend fix from frpythoneers is to wrap the
select (and socket, respectively) calls in a loop:

while True:
  try:
    select.select(...)
    break
  except select.error, v:
    if v[0] == errno.EINTR: continue
    else:        raise 


It's probably more appropriate to put the
exception-handling *inside* select.select (and
socket.socket) but that's beyond my expertise...
