Parallel simulations in threads

[bejito]

Hey !
I wanted to run multiple simulation in parallel using threading, but it seems to fail... I'm getting something like

Call-back cb_f_in_zvode__user__routines failed.
[1]    99317 segmentation fault (core dumped)  python plap.py

I found this issue in qutip which sounds like it could be related. It seems to be an issue inherited from scipy

This seems to work with multiprocessing though.

I'm not sure if there are any workarounds using threads. Did any of you encounter this before ?
