IMHO: if I want something in Linux I just write the app I want
if I cannot find it. ..
....you have all of the kernel source code and it may be
possible to implement this in the kernel. The kernel currenly
has how much memory a process is using, it may be possible to
have the scheduler (?not the best place?) check the memory that
a task is using and if it has exceded a defined limit then do
something like kill the process, this could be done something
like
#ifdef __MEMORY_LIMIT__
if (tsk-> what is that memory parameter > set_limit) {
do what ever
}
#endif
set_limit could also be a parameter that is changed in the /proc
file system. if the value in the /proc is null it has no
limits..
this may be a topic for discussion on the kernel mailing list,
as this is not necessarily SMP specific....
the only problems here is that if a process does not excede the
limit and the scheduler schedules it, then as the process starts
its run it could excede sys limits
(hehehe.. use the source Luke....)
