Assert failure found in 8.1RC1

Hey all,

While trying to get a reproducible test case for my CS storm problem (see
http://archives.postgresql.org/pgsql-hackers/2005-10/msg00585.php), I upgraded
to 8.1RC1 and encountered the following assert:

TRAP: FailedAssertion("!(shared->page_number[slotno] == pageno &&
shared->page_status[slotno] == SLRU_PAGE_READ_IN_PROGRESS)", File: "slru.c",
Line: 309)

On the good side, I'm yet unable to get a sustained CS storm anymore with this
level of code. Looks like something might changed for the better in the last 2
weeks?

For the assert, I had 5 sets of my app running, each with 8 potential
outstanding queries. I then threw my test at the db with 20 more queries, and
took the above failure.
