Mostly safe_memset is called from pool_alloconly_clear.

I attach result from oprofile - functions (with call tree) that have 
more than 2% of all oprofile samples in libdovecot.so.

p_strdup is on the list, but it is lower than before last optimisations.
As You see there is no other optimised functions :)
