    linux allocate a lot of buffers in memory in order to speed all
    disk-accesses. this memory allocated to buffer is aimed to shrink very
    quicqly if any process needs and use a lot of memory, so you don't have
    to bother about this memory.

    by the way, do not forget also that part of the memory counted as used
    by a process may be shared (libraries), not to say that I don't know
    how is counted the memory "occupied" by say a mmap call that map a file
    into memory (for example). Is the said memory counted as allocated ? as
    buffer ?
