Hello

Recently I have made some lenghty calculations  on Win95 (P166MHz) with
32Mb RAM and 300Mb swap.

Calculations sometimes used up to 240Mb. (when tested with
MaxMemoryUsed[]) Everything was fine with functions like ExpToTrig,
Expand, TrigToExp, Factor,  etc., but not with Simplify or
FullSimplify. It looks for me that this two functions can not use  swap
at all and exits with "Out of memory" message when all physical memory
(32Mb is loaded). If stated abov is true, then it would be interesting
to know all functions which can not use swap in order to save time.
