[Asterisk-Users] Compiling while * is running

[Clif Jones]

It was actually a good question.  When I learned Unix internals, the 
shared libs and executables
where "busy" when loaded because of swap-in/swap-out requirements.  Swap 
space was
used to store the core memory for the apps, and the app itself was 
memory mapped when
needed.  That is why you couldn't overwrite it when it was in use.  You 
had to rename it.
I guess Linux has worked around this.  Wish I had time to look and see 
how. :)
