Yes, when done based on what is available then there is a
problem when we run out of free ones because we do not
know which one to replace. I was thinking of something like
this,
1) DT would give a list of all free ones, and also if some are
mapped as default and not used, mark those also as free.
2) While mapping see if it has a default mapping and use it.
otherwise, pick from free list.
This should be ok right ?

Sricharan
