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.
