Subject: asyncs.test intermittently fails in "preemption via sigprof"
Date: Tue, 19 Jan 2021 20:18:29 -0600

When 3.0.5 was uploaded to the Debian buildds, the amd64 build failed
like this:

  ERROR: asyncs.test: preemption via sigprof - arguments:
  ((wrong-type-arg #f "Wrong type (expecting ~A): ~S" ("resumable
  continuation" #<vm-continuation 7faf49c99350>) (#<vm-continuation
  7faf49c99350>)))

For example:

  https://buildd.debian.org/status/fetch.php?pkg=guile-3.0&arch=amd64&ver=3.0.5-1&stamp=1610521112&raw=0

It was easy to reproduce locally on a Debian bullseye system (also
amd64, though of course the architecture might not be relevant):

  (while ./check-guile asyncs.test; do sleep 0.1; done)

This would reliably fail with the same error after a handful of
attempts.
