No, I remember that Falcon was shipped with Multitasking operating system
with adaptive priorities scheme (well, I can't write it exactly, my RAM is
not that good). Basically an application having keyboard I/O (or being in a
top window?) should get higher priority (perhaps not visible in top).

When I am thinking about it now - it might have been a feature of AES 4.0,
not MiNT kernel itself...

you mean disk I/O? How can you measure that in MiNT?

what's /ram? and what is the -pipe option? I need to speed up my compilation
time - my development cycles are too long (usualy two to five minutes of
recompiling PARCP or Atari800 - I hate that!)
