[issue33725] High Sierra hang when using multi-processing

[Ronald Oussoren]

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

A better solution is to avoid using fork mode for multiprocessing. The spawn and fork server modes should work fine. 

The underlying problem is that macOS system frameworks (basically anything higher level than libc) are not save wrt fork(2) and fixing that appears to have no priority at all at Apple.
