Cython and interrupts
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.
Requirements
Python >= 3.6
Cython >= 0.28
Sphinx >= 1.6 (for building the documentation)
PARI/GP (optional; for interfacing with the PARI/GP signal handler)
