I really can't understand why winXP reports more than 2GB free and
refill the swap-container with about 256 MB all the time.
Seems it tries to have a backup of the OS-core for the next
(anyway soon expected) crash available on disk.

[..about code performance]

Yeah, low level optimisation makes only sense if the overall
performance is kept in mind. Loop unrolling and heavy bloat
as a reason for speed often end up in several seconds delay
caused by disk-load and pagefault swaps.

A speed/size compromise beside tiny resident code modules
is my way for faster Apps and OS-functions.
