Related,
I've always wondered how I could limit the amount of Memory (or VM)
for a process. E.g. give netscape 80MB max.
I have tried ulimit -m N and similar flags in a wrapper script
for netscape. But it doesn't work as I want: netscape will grow
until it reaches the limit and then die due to lack of memory.
I want the kernel to somehow masquerade to the process that the machine
has less VM than it really does, thereby hopefully inducing netscape to
free(3) more often...
Thanks,
Karl Runge
