Can someone please explain to me why the following trivial program
shows up on both a `ps' listing and also when using `top' as having
a size of 136 KB?
-------------------------------------------------------------------
#include <unistd.h>
int
main (int argc, char *argv[])
{
sleep (60);
return 0;
}
-------------------------------------------------------------------
Using the `size' command, the program itself, even when linked (with
the shared libraries) only has a trivial size of around 8 KB.
So where the dickens is that other 128 KB of per-process overhead coming
from?
Note: This is NOT just an academic question. I need to run a LOT of
identical (small) processes, and this overhead is killing me bacuse I
really do not have enormous amounts of main memory available.
