Usually you can get away with remote login if it is X that locked up,
with a frozen kernel you have less options.. ctrl-alt-F1 sometimes?

attempt G_malloc(),G_free() of estimated size before processing. Back in
the mailing list archives somewhere I figured out the current bytes per
vector point needed (with valgrind) and suggested this?

I don't know how to query available memory in a cross platform way.
