There were some errors with how libsigcx handles events - the attached
patch fixes them.  Here's the changelog entry from the attached patch:

          * sigcx/dispatch.cc, sigcx/dispatch.h: Fix iterator corruption
          and calling removed handlers when removing event handlers from
          event handlers, and fix not select()ing on the first pass on
          file event handlers added from event handlers on the same pass.

With these patches and the current arch tree, my stuff is working quite
well.  It'd be great if a 0.6.5 could be rolled from the arch tree after
this is applied.  If it's a time issue for you, I could see about
rolling one for you.
