In more recent testing after the committed md_ioctl32 fix,
including the 14.0-ALPHA1 snapshot:

A) I no longer get the [300.015s] or longer timeouts.

B) I instead get "failed: Setup failed" in under 1 sec for
   those test cases.

C) I no longer get any hung up processes being left behind.

(C) is likely expected, given the (A) -> (B) change.

It does not look like this report will ever progress to a
bugzilla submittal, given what is observed in the
14.0-ALPHA1 snapshot.
