I've bumped the time limit up to 25 minutes, but it still gets cut off before the parallel tests complete, and the progress indicator isn't any further along than it was with the 15-minute cut off. See this log.

On my system, the IPython.parallel suite completes in 90 seconds (195 tests, no skips), so I think something is getting stuck.

For now, I've disabled the parallel tests (removed the --all flag) so that we can use the rest of the test suite.

The Windows tests appear to have had the same problem, and it waited 2 hours before aborting the build. Also disabled parallel tests there.

@minrk I'm still seeing this on Linux on ShiningPanda (timeout after 25 minutes), although it seems to be fixed on Windows. I've had to disable --all again.

It's extra annoying, because we don't get failure e-mails for builds that are aborted due to a timeout, so it fails silently.

Merge pull request #4270 from minrk/task-timeout
795c9e3 
adjust Scheduler timeout logic

Timeout starts when task submission is attempted. That is, it starts each time in resubmit / retry cases.

Avoids issues of timeout firing only once while a task is pending, when it might come back and be retried after the timeout has fired.

Also adds a ten second timeout for sync calls in the tests, which should hopefully avoid hangs when things are misbehaving.
