Subject: Only send SIGXFSZ when exceeding rlimits.
From: Micah Cowan <micah@xxxxxxxxxx>
Some users have been having problems with utilities like cp or dd dumping
core when they try to copy a file that's too large for the destination
filesystem (typically, > 4gb). Apparently, some defunct standards required
SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it
for when a written file exceeds the process's resource limits. I'd like to
limit SIGXFSZs to the bare minimum required by SUS.
