I just noticed that there has been a critical bug identified in the
Boost.Function library when it is used in multi-threaded context. We do
use this for Pion... heavily and across multiple threads. Haven't
noticed any problems with it (that I know of at least), but we should
probably patch our computers with the fix that is posted on the
boost.org home page.

FYI, I just compiled a new source tarball for Boost (1.34.1) with this
patch, ASIO 0.3.9, and also with our own Cygwin patches incorporated.
It's available at http://pion.atomiclabs.com/files/boost_20080126.tar.bz2.

Take care,
