Description Jacob Hunt 2013-04-03 19:46:55 UTC 
Description of problem:

SocketServer's handle_request function uses "select" call to handle io, but sending POSIX signal will result in 'Interrupted system call' exception raised.

Version-Release number of selected component (if applicable):

python-2.6.6-36.el6.x86_64
