I just built this pan 0.133 from svn using exactly the same ubuntu 8.04
gcc version and I still see no such problem.

Describe again exactly what you see when updating headers, and when you
see it.  Does the header pane *ever* rethread, even once, at the end of 
the first 10 seconds?

Have you tried strace during the long pause?  If you start pan in gdb
and hit Ctrl-C during the busy time you can type 'bt' to see what part
of the code is running at that point.  You need debugging symbols for
that, though.  Charles uses the -g flag by default to build pan, but
if the offending code is in some other library you won't get as much
info, but at least you can see what library the offending code belongs
to.
