Parallel virt-df and virt-alignment-scan tests sometimes deadlock

Description of problem:
virt-df and virt-alignment-scan tools normally run with
multiple threads, up to 12. These tools are tested by
the libguestfs test suite, ie. 'make check'.
When running the libguestfs test suite, there is a deadlock
happening which causes these tests to fail. It mostly happens
when the tests run in Koji.
See the attached build log for a typical example.
Version-Release number of selected component (if applicable):
libguestfs 1.24 & 1.25
Quite often but not 100%
Steps to Reproduce:
1. Run 'make check -C df' and/or 'make check -C align'
