And change the default value to 5min.
I have noticed that initializing 88 Python workers on a machine with 88 logical CPUs and an NFS filesystem can take 20 to 30s. Therefore I think using 10s as default worker timeout is too low to be useful on large computing servers. I think 5 min is a more useful default value.
I think 5 min should also be the default value for loky itself.
