Not your question, but is this left as-is or will this be handled too? Eg.
BR69346 was victim of this. Might be unlikely for 'normal' services, but
DCOP'ing with plugins, that use both DCOP (eg. nspluginviewer), makes sync
call unusable. I.e. for non-threaded apps, how likely is it that if one
calls app A and, waiting for a respond, it receives a call from A, it does
_not_ deadlock?
