Patch is attached.

I'd like to get some comments about this patch. Does it seem
reasonable enough to accept? Is there a better way to handle it?

BOOST_VERIFY aborts on EINTR, but EINTR is usually not fatal, it just
means you need to try later.

So, the attached patch makes it so that the condition_variable and
mutex error checks retry on EINTR, but will still fail on any other
error.

This issue was uncovered on one of Phusion Passenger's customers'
production systems.
