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

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...
