    23 ||'''Steady'''|| normal operation; no additional swap space is needed, nor do we have
    24 more than is needed.  However, the program can go into the hungry or overfed
    25 states at the drop of a hat.||
    26 ||'''Hungry'''|| more swap space was recently allocated.  The program is willing to
    27 allocate even more if needed, but it will not consider dropping unneeded swap
    28 files.  After a certain timeout period, the program reverts to the steady state.||
    29 ||'''Overfed'''|| significantly more virtual memory is available than is needed.  If
    30 this situation persists for a certain timeout period, a swapfile is deallocated
    31 and the program returns to the steady state.||
    32 ||'''Diet'''|| a recent allocation attempt has run into resource limits, e.g. because
    33 the filesystem used for swap files was full.  No more swapspace can be allocated
    34 but excess files can be freed up very rapidly.  Afer timeout, reverts to steady.||
