I fixed it just after we discussed it on IRC, in commit 134c95f of
stable-2.0.

Thanks again for the report!

Hello,

in the following example, the cores, 4 in my case, are used for a couple of seconds,
then at some point only one core is used:

guile -c '(begin (use-modules (ice-9 threads)) (par-map 1+ (iota 400000)))'

Cheers,
David
