Subject:	Re: virtual memory

Trieste, August 16th 1993

It means that you can allocate memory that you don't have (well, you
must have sufficient free disk space): gcc lets you use transparently
disk space as it was memory (I mean RAM). You can allocate up to 128
MB of disk space: try alloc(4000000) or compile the program pagetest.c
which comes in /gcc/samples/pagetest directory and run it increasing
each time the command line parameter. For a more technical discussion
you should ask DJ: he could give you more interesting informations, such
as the allocation strategy used by the dos extender (LRU for example).
