python-cysignals

When writing Cython code, special care must be taken to ensure that the code can be interrupted with CTRL-C. Since Cython optimizes for speed, Cython normally does not check for interrupts. For example, code like the following cannot be interrupted in Cython:

    while True:
        pass

The cysignals package provides mechanisms to handle interrupts (and other signals and errors) in Cython code.
