Still encountering this occasionally - seems to be epoll related. I've not gotten it via either poll or select (yet).

In a local module that I use (which calls out to svn), switching from Python 2.6's subprocess module to subprocess32: http://pypi.python.org/pypi/subprocess32/ appears to fix this problem.
