Today I learned about this magic variable in MacOS.
export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
If you don't set this, there is a good chance your python code will crash if you do a fork(), some stuff, exec().
objc[53913]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
I learned about this with help from a person on slack named 'Fabulous Nuggets', and found more details on this blog from 2018.
