Holding the GIL for too long could disrupt the heartbeat due to non-copying sends.

The following cell repeatedly calls a function that holds the GIL for five seconds.

The heartbeat will fail after a few iterations prior to fixing Issue #1260.

import time

from cython import inline

    """gil-holding sleep with cython.inline"""
    code = '\n'.join([
        'from posix cimport unistd',
        'unistd.sleep(t)',
    ])
    while True:
        inline(code, quiet=True, t=t)
        print time.time()
        sys.stdout.flush() # this is important
