On a multiuser system a single user can cause a lot of damage to himself
and the rest of the users by running a process with a huge memory
fingerprint, thus resulting in wastage of the users' time and
resources.  This is just one of scenario, there many in real life.  So
while I also find it angering when after hour of running the command
runs out of stack, one should keep in mind that this is a double-edged
issue and the balance in tradeoffs is the key.  Reliable
pre-estimation of required stack would be the best solution, but maybe 
it's too much to ask in a general case.
