This was probably used because the gethostbyname() function is not
thread-safe. On Solaris you can perform thread-safe lookups using
gethostbyname_r() and similiar functions (see man pages).
It should be easy to modify OmniNetworking to use these functions.

How the reentrant functions can be used can be seen in the
NGInternetSocketAddress class of the NGNet kit available in

  ftp://ftp.gnustep.org/pub/gnustep/contrib/MOF2-fd-1998-12-28-fixed.tgz

(a similiar kit like OmniNetworking but intendend to be used with
GNUstep).
