Subject svn commit: r834130 - /apr/apr/trunk/test/testpoll.c
Date Mon, 09 Nov 2009 16:16:10 GMT
Author: trawick
Date: Mon Nov  9 16:16:06 2009
New Revision: 834130

URL: http://svn.apache.org/viewvc?rev=834130&view=rev
Log:
fix incorrect assumptions in pollset/pollcb tests:
- polling won't necessary detect the status change immediately
after an I/O operation
- a single poll call won't necessarily return multiple status 
changes after multiple I/O operations
