OK, I did that after restarting the make (since I had killed the 99% process).
Had to use sudo or it didn't work:
$ sudo strace -p 63131
Process 63131 attached - interrupt to quit
(no more output at all though that process is still using 99-100% of a CPU).
For the parent process (also python with same command line, presumably
before it forks) I get
$ sudo strace -p 62320
Process 62320 attached - interrupt to quit
select(0, NULL, NULL, NULL, {0, 12082}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 50000}) = 0 (Timeout)
(repeating for ever)
