1.5.1 (1.5-release tree from 2-July)

Good question; I didn't have the serial port plugged in, and it isn't
usually physically accessible, so I couldn't see what the in-kernel
debugger said. I've since made sure savecore runs on restart.

I'm running (or trying to run) sieving software (SNFS, Special Number
Field Sieve) which allocates a 64 meg block and walks all over it. It
doesn't swap well, and is a really good way to test memory.

Very. I've rebuild the source tree at least a half a dozen times with no
compiler errors (except when I've forgotten to unlimit).

I guess I should look at a system core before I delve into trying to fix
the problem, but I thought I'd get some feedback about the current
practical limit on data size.
