After upgrading to the new pssh 2.1 package, the app is crashing on me:

[darose@daroselin ~]$ pssh -h hosts.txt -l root -i uptime
[1] 11:33:27 [SUCCESS] <one of our hosts>
16:32:49 up 90 days, 18:04, 0 users, load average: 0.00, 0.00, 0.00
Traceback (most recent call last):

data = os.read(errpipe_read, 1048576) # Exceptions limited to 1 MB
OSError: [Errno 4] Interrupted system call

This happens repeatedly.

Downgrading to 2.0 makes the problem go away.
