Follow-up Comment #8, bug #44555 (project make):

I see absolutely the same results as noted.

And there is NO DOUBT that the fork/vfork is to blame!

I tested today on any single commit since 3.75(over 1000 versions!), and every
single one of those versions up to 94735f0ad7f67c56afa1513381c73e8f62cd44fc
(3.82+156, i.e. the 156th commit after 3.82) had almost identical results,
where at that version it suddenly bloated to those tedious time-frames noted
by others.

To summarize: bring back vfork()!
