  performance hint: sksparse/cholmod.pyx:379:5: Exception check on '_error_handler' will always require the GIL to be acquired.
  Possible solutions:
  1. Declare '_error_handler' 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 '_error_handler' to allow an error code to be returned.
