We don't need to send the temporary xsearch {git} object over to
workers, just the directory name.

This lei2mail segfault turned out to be an old Perl 5 quirk
which plagued many before me. It was not consistently
reproducible, and random changes seemed to make it happen more
or less frequently. There were several times when I thought I
fixed it (and maybe this is still one of them!) only to have it
pop up again.
Still, I found many other little bugs and improvements worth
doing along the way. Hope things go more smoothly in the
future...
Anyways, [PATCH 18/21] is the fix (and I'll followup with more
on how I found the fix). 19/21 is purely defensive
future-proofing.
Eric Wong (21):
lei: more consistent dedupe and ovv_buf init
ipc: switch wq to use the event loop
lei: remove per-child SIG{__WARN__}
lei: remove SIGPIPE handler
ipc: more helpful ETOOMANYREFS error messages
lei: remove syslog dependency
sharedkv: release {dbh} before rmtree
lei: keep $lei around until workers are reaped
lei_dedupe: use Digest::SHA
lei_xsearch: load PublicInbox::Smsg
lei: deep clone {ovv} for l2m workers
sharedkv: lock and explicitly disconnect {dbh}
lei: increase initial timeout
sharedkv: use lock_for_scope_fast
lei_to_mail: reduce spew on Maildir removal
sharedkv: do not set cache_size by default
import: reap git-config(1) synchronously
ds: guard against stack-not-refcounted quirk of Perl 5
ds: next_tick: avoid $_ in top-level loop iterator
lei: avoid ETOOMANYREFS, cleanup imports
doc: note optional BSD::Resource use
