I´d rather go with "pre-paid" small stack than a larger one and then
allocate from heap when necessary to get more. This way the applets that
doesn´t require so much memory doesn´t need to "pay" for the stack they
doesn´t need. If there are many concurrent processes all having big stacks
the memory may be eaten out pretty quick... I remember Amiga OS used to
have default stack size per process something like 4K in the early times
and that machine sure could run dozens of processes concurrently if needed...
