On a UNIX system with a reasonably modern VM it should be more efficient 
than this.

When a tex (or any other) process exits, its pages in memory won't be 
"unloaded" but merely left alone. If memory becomes low in the future, 
the VM page scanner will discard those pages later (if they've been 
modified they will need to be paged out to storage first, of course)

When the next tex process starts up, the text and BSS pages it needs 
should be sitting there in memory for it to use, from the previous 
invocation.

Of course, there's more to fork/exec than just loading the code/data, 
but not too much more.
