performance hint: src/cysignals/tests.pyx:94:5: Exception check on 'infinite_loop' will always require the GIL to be acquired.
Possible solutions:
1. Declare 'infinite_loop' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
2. Use an 'int' return type on 'infinite_loop' to allow an error code to be returned.
performance hint: src/cysignals/tests.pyx:101:5: Exception check on 'infinite_malloc_loop' will always require the GIL to be acquired.
Possible solutions:
1. Declare 'infinite_malloc_loop' as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
2. Use an 'int' return type on 'infinite_malloc_loop' to allow an error code to be returned.

2. Use an 'int' return type on 'dereference_null_pointer' to allow an error code to be returned.
