I've had a poudriere-devel bulk run on a Pine64+ 2GB get a: "Warning: Failed to acquire update_stats lock"

Not sure why it's happening exactly. It tries to create a directory in
the internal tmpdir if it doesn't exist already wrapped basically by
lockf(1) with a 30 second timeout.

Anyway it's completely harmless. It just means the stats displayed there
may not be accurate for another few seconds.

What's likely happening is that the separate html json writer process is
still working with the lock held and your SIGINFO timed out waiting for
the lock - or the other way around. Harmless.
