In many Gnu projects, the 'configure' script is the biggest barrier to
building because it takes soooo long to run. Is there some way that we
could improve its performance without completely reengineering it, by
improving Bash so that it can parallelize 'configure' scripts?
For ideas about this, please see PaSh-JIT:
Kallas K, Mustafa T, Bielak J, Karnikis D, Dang THY, Greenberg M,
Vasilakis N. Practically correct, just-in-time shell script
parallelization. Proc OSDI 22. July 2022.

I've wanted something like this for *years* (I assigned a simpler
version to my undergraduates but of course it was too much to expect
them to implement it) and I hope some sort of parallelization like this
can get into production with Bash at some point (or some other shell if
Bash can't use this idea).
