it is pretty standard for this old AMD 2800+ system... at least for now, anyway...

i think the thread thing would be the better way to go... we will never know 
what may be going on on a user's machine... consider one that is swapping 
excessively, for instance...

i was looking more at the rendering process possibly having been run and just 
waiting to be displayed...

as another test: i just loaded task manager so i could watch memory usage...
with all my normal tasks loaded... ~499460M used
started lazarus... followed same path as before...
   reading compiler options: 18 and something seconds
   rendering: .172

memory consumption in the above was negligible... i ran it again thinking that 
it would all be in the disk cache and thus load faster... lazarus loaded in less 
than half the time it did previously but reading the options still took 18 
seconds... memory consumption is sitting at ~535235 now... up slightly from the 
499xxx figure above...

considering that this is a 2Ghz (2083mhz) machine, i'm not sure where to look, 
really... PATA HD... defragged at least once a week...

maybe i'll try unloading avast and seeing what that gets me... i'm really loath 
to unload the firewall but that, too, can be done... i guess i'll just pull the 
network cable loose, first ;)
