daemon shutdown time with large zones (bind 9.2.4)

For my environment, compiling with -DISC_MEM_USE_INTERNAL_MALLOC does
improve the situation I was describing by about 62 seconds, or about 13%
of the original time.

If unloading an 81mB zone on other platforms take just seconds, I guess
there must be something else going on here :)

Thanks for the hint, it was helpful!
