qemu 6.1 iotests hanging intermittently

It seems like the qemu test suite now hangs intermittently after
running iotests.  Here are some examples:

(on x86-64)
...
  TEST   iotest-qcow2: 313
  TEST   iotest-qcow2: nbd-qemu-allocation
  TEST   iotest-qcow2: qsd-jobs
Not run: 181
Passed all 122 iotests

(on i686)
...
  TEST   iotest-qcow2: 292
  TEST   iotest-qcow2: 299
  TEST   iotest-qcow2: 313
  TEST   iotest-qcow2: nbd-qemu-allocation
  TEST   iotest-qcow2: qsd-jobs
Not run: 172 181 186 192
Passed all 119 iotests

(on i686)
...
  TEST   iotest-qcow2: 292
  TEST   iotest-qcow2: 299
  TEST   iotest-qcow2: 313
  TEST   iotest-qcow2: nbd-qemu-allocation
  TEST   iotest-qcow2: qsd-jobs
Not run: 172 181 186 192
Passed all 119 iotests

The code that invokes the tests is:
https://src.fedoraproject.org/rpms/qemu/blob/rawhide/f/qemu.spec#_1725

I'm not sure exactly why.  It seems like the next line of output
should be "popd" which is a trivial bash command and so shouldn't take
too much time.

This seems to have started to happen round about the time qemu 6.1.0
was released.
