Re: how to forcely release heap in UNIX

This just says what UNIX does it does not say why you might need this.
And the article by Eric Sosman that is referenced only suggests that you
probably don't need to worry about this.

and one another question. when will actually this memory be released
to the os. is it possible for OS to force the process to release this
memory? otherwise it might waste a lot of memory for a program that
allocates a huge chunk of memory in the initialization and frees all
of it, but never reallocates memory for its life time. (this is the
problem im having).
