malloc memory stuck

[DanKarron at UCBVAX.BERKELEY.EDU]

I was tracing a bug in my program that caused a HUGH (almost, but very large)
value to be calloc'ed. The program crashed with a big core dump, but I just
noticed that gr_osview shows all the memory in core being used as userdata.
I have 32mb.

The program is dead and gone, and any memory that is tried to allocate should
be freed. This is using the libmalloc.a version malloc, and I
will have to reboot my kernel if there is no way to unlock(unpin ?) those
pages of memory. My machine is now swaping for everything. Performance
is poor, and a crash in malloc should free any memory it tried to acquire.

This might have something to do with other reports here on the net about
too much memory being used apparently for nothing.
