The limit is reset because netscape is invoked from an attachandrun
script, and attachandrun is setuid. (On IRIX, limits are reset on
exec of a setuid program). So, perhaps we should consider doing one
or more of:
- Change our netscape wrapper script to make use of the COREDUMPSIZE_LIMIT
environment variable hack we added to cshrc.
- Change attachandrun to know about COREDUMPSIZE_LIMIT.
- Change the kernel's default core limit to 0.
