Got it.   So while the mythconverg_backup.pl script itself might take a
long time, the database locking time is minimized.

Perhaps a better modification for me might be to dump the database to
local storage first, and then pigz it to its final resting place.  And
yeah, I'm assuming that my use case is specific enough to not warrant a
change in the script mythtv-users-wide.
