Depends on the operating system.  In some cases you need to rebuild the
kernel, in others there is some sort of kernel tunable parameter
altering which may or may not require a reboot.  In Tru64 it's the proc
subsystem in sysconfigdb, and you do need to reboot for it to take
effect.

I don't know what the limit is for Linux-i386, although there is an
ultimate limit of 4GB RAM per process, due to the 32 bit nature of the
operating system.
