It passes sometimes and fails sometimes.  Here's the weird failure I
need to debug:


https://api.cirrus-ci.com/v1/artifact/task/6033765456674816/log/src/test/recovery/tmp_check/log/regress_log_032_relfilenode_reuse

Right at the end, it says:

Warning: unable to close filehandle GEN26 properly: Bad file
descriptor during global destruction.
Warning: unable to close filehandle GEN21 properly: Bad file
descriptor during global destruction.
Warning: unable to close filehandle GEN6 properly: Bad file descriptor
during global destruction.

I don't know what it means (Windows' fd->handle mapping table got
corrupted?) or even which program is printing it (you'd think maybe
perl?  but how could that be affected by anything I did in
postgres.exe, but if it's not perl why is it always at the end like
that?).  Hrmph.
