Could also be CPU count or CPU speeds since IPC bugs are
sensitive to that.  That said, I can't get cindex.t to fail
with 1, 2, or 4 cores enabled in the QEMU VM.  But I am on
some ancient Athlon CPU that CentOS warns about on bootup.

Yup, only had xapian 1.4.22 before but 1.4.24 also succeeds for me.

Also, it works both with/without xapian14-core-devel libs
and after `rm -rf ~/.cache/public-inbox/inline-c/*c++*'
to force a rebuild.

It should switch between Xapian Perl bindings and C++ xap_helper
depending on whether the -devel libs (and g++) are available,
which is fine for tests.  The C++ version is basically required
for working with lore + git.kernel.org volumes, though...
