WARNING: pgstat waiting

I'm playing with 9.2devel, and I can fill my logs with:

WARNING:  pgstat waiting for 5001623 usec (494 loops), file timestamp 368986878169601 target timestamp 368986897680812

I see its from here:

http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=79b2ee20c8a041a85dd230c4e787bef22edae57b

So I was wondering if there is anything I can help with?  Not sure if you need a reproducible case, or something you'd
likeme to try?
