executable caching?

Are frequently used programs cached in memory somehow?

I've got a little tcl app that calls ping every second. It breaks my heart
to *hear* the disk take a hit every time ping is called. Is there a way to
lock ping into memory, preventing a disk hit everytime it is called?

Things sound really ugly when a dozen users call this app!

I tried creating an MFS, and placing the ping executable in it. But I can
still hear the disk grind everytime ping is called -- which really
surprised me. Setting the sticky-bit doesn't help either. (The Archives
say that the sticky-bit on executables is not honored by DEC-UNIX. Why?)

Confused and worried about disk life,
Salil
