O'm new to the list, so Im not sure if this has been covered, but someone
can crash any system with a few lines of code. (tested on UNIX, LINUX)

Gcc it, run it and whatever system your on will crash. Is their any way
to stop users from doing this? I.e. restricting number of process that
can run?


Try changing the setrlimit() in login.  In particular, I think you might want
to set RLIMIT_NPROC to something small like 60.  That way, any programs spawned
by login (and its child shells) will have that hard limit.
