Summary: SQL: crash on concurrent use
Initial Comment:
A simple script has been added to the monet4/ backend.
It supports simple testing of concurrent access to the
server.
The call
script.sh 2 0 20 example.sql
is sufficient to crash the server.

Romulo,
no need to be "shy", just go ahead, re-open the bug and make it a SQL bug,
if you think that's what should be done!

The bug needs to be open.
In M5 and M4-SQL stable crash with the script call.
I would like to move this script to the BugTracker in SQL because is not
specific bug of M4,
am I allowed to do that?
Regards,
Romulo

Status set to "pending", as we should check whether we could
add this script to the test collection.

concurrent access to the cache of catalog information wasn't
save. A second problem was that the query cache wasn't
cleared after each schema update, this is now fix by
checking a global
schema number at the start of each transaction.
