Ah, took me a while to realize what was going on :x
The Xapian files processes were lacking O_CLOEXEC and FD_CLOEXEC
usage and this was a problem in Xapian >= 1.2.21 && <= 1.2.24

Relevant Xapian commit should be e953a10dc4f0cc8e604fd2082c87b638c6a3382b
("Set CLOEXEC on the lock file fd and pipe")

I suspect the following patch works around the problem with or
without parallel=0

Can you confirm?  I don't have 1.2.22 handy anymore, but I
reported this problem and got Olly to fix it back in 2016.
Thanks.
