tried that, doesn't work. The timer fires on the same thread it has been
created. So if I block the thread via nsIchannel::open()...
I tried to create the timer on a separate thread
(nsIThreadManaher::newThread), but deadlock when creating a
dispatch-proxy (on trunk only, need to mark the target object
nsIClassInfo::THREAD_SAFE). Please have a look at the attached code, any
ideas?

"network.http.request.timeout" in that doc
thanks for comments,
