@nedbat Got it: print(sys.executable) from multiprocessing prints the system PyPy in 7.3.15, but the venv onein 7.3.14.

A reproducer, no coverage used:

import multiprocessing as mp  
import sys

def worker(a):  
 print(sys.executable, "worker python")

if __name__ == "__main__":  
 print(sys.executable, "main python")  
 mp.set_start_method("spawn")  
 p = mp.Pool(3)  
 outputs = p.imap_unordered(worker, [(x,) for x in range(6)])  
 p.close()  
 p.join()
