Hm... there IS a hidden one!

Tcl core still uses MT-unsafe gethostbyname. If we'd to use the
gethostbyname as well, no matter how protected we have made it
within our process, the chances are we'd end up trampling on
each other feet.

On the short term I prefer this one. On the mid term I will replace
the gethostbyname calls in Tcl core with something like dns.c in
NS today.
