Thanx Anthony.
According to 'man 2 brk',
brk sets the end of the data segment to the value speci
fied by end_data_segment, when that value is reasonable,
the system does have enough memory and the process does
not exceed its max data size (see setrlimit(2)).
So, if I'm understanding this correctly, SIZE indicates how much memory
has been reserved for the application (and therefor not available to
other applications), while RSS is the amount of memory currently being
used by the application.
