File leaks in nosebook

[gramster]

Make a bunch of notebooks with failing tests and run with nosebook. After a few fail you start getting kernel creation failures along the lines of:

ERROR: Failure: OSError ([Errno 24] Too many open files: '/var/folders/00/17c28000h01000cxqpysvccm004xh9/T/tmpImZYO5.json')

Traceback (most recent call last):

It seems like test failures leak files.

I tried adding a manager.shutdown_kernel() in a finally block in loadTestsFromFile but that was insufficient to fix this.

Ooh, thanks! I'll look into it!
