Thanks for sending the strace output. It contains the following:
,----
| write(1, "\33[K38.0% laying out Number\r", 27) = 27
| ...
| clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x7f6adf0ae9d0) = 2039
| ...
| wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}],
WNOHANG|WSTOPPED|WCONTINUED, NULL) = 2039
| ...
| wait4(2039, 0x7fffeb29ded4, 0, NULL) = -1 ECHILD (No child processes)
`----
which means it's trying two times to get the return status of the child
process. This looks like it may be an issue with gevent, which started
reaping child processes some time ago.
I'll try to reproduce the issue and fix it.
