Good point.

Glib, SDL and APR (Apache Portable Runtime - http://apr.apache.org/) all
have portable thread support. APR has the advantage of lots of
network-related stuff we could use, while SDL is already used by all
clients for sound, and Glib is already used by GTK client. Both APR and
Glib could be used to outsorce some utility/ functions to an external
library. I think APR and SDL are smaller and more portable than Glib, and
both are present on many systems already.

But this is really a blue sky item anyway...
