You REALLY need to check for memory leaks in the programs which are
not expected to finish "any time soon", like an X server (which can
stay up for weeks) or some bank transaction processing environment
(which is SUPPOSED to stay up for long periods of time and you would
not want it to say "can not allocate more memory" only because you
keep forgetting free() something allocated for each processed
transaction).

Speaking about retaining allocated memory cache after program
finishes, I can IMAGINE a way to make this memory cache belong to
shared library (glib.so) instance (via shared memory
allocation/deallocation) and slices of that mapped into given process
address space whenever needed, but I doubt GLib would go that far in
augmenting/replacing UNIX VM layer. ;-)
