bug#67370: FAIL: asyncs.test: preemption via sigprof (nondeterministic test failure)

Hi,

I'm sometimes getting this test failure when running on the tip of the
main branch, commit: d579848cb.

The test does not seem to fail when run individually (via './meta/guile
-L test-suite -L . test-suite/tests/asyncs.test').

Guile was configured using './configure --enable-mini-gmp'.

It seems relatively rare on my 4 cores system, using something like
'make check -j5'.  I've just re-run the test suite 4 times without the
problem.  I've seen it at least twice in the last 3 weeks though, so I'm
reporting it.
