swap or memory leak on recent master?

[Matthew Dillon]

    Well, the kernel memory allocator itself doesn't use swap, so it is
    more likely a runaway user program (?) and not the kernel.  If tmpfs
    is being used it could be something filling up the tmpfs mount, including
    possibly a process with a descriptor open on an unlinked file.  That's
    all I can think of.

    Under normal operation idle processes will eventually wind up getting
    paged out since there is no sense tying up ram to hold them.  e.g.
    things like getty and such, but these normally do not amount to very
    much use.
