As mentioned, the original crash was observed with the stock Solaris 8
3.23.52-Max binary. The result was the same, just without a gdb-able
backtrace.

Just to confuse matters, I put the install back to 3.23.42 and could
still make it fall over with a stream of INSERTs (just input from a
local client and not even the slave thread) and a RESET MASTER
concurrently. So, either we've been living very, very luckily for about
a year, or this is a problem specific to Solaris 8.
(The old installation, which suffered from a number of bugs but never
this one, was Sol7/3.23.42)

My job is currently to fix this, so I'll try to spread some test cases
around a selection of machines to find more information.

Cheers,
-Matt.
