611538 - Switch to lazy creation of WYCIWYG channels

Status: RESOLVED INVALID

(Core :: Networking, defect)

So I see that nsHTMLDocument::OpenCommon always creates a WYCIWYG channel.  But these never get used unless Document.Write() is called, i.e. the vast majority of the time. Is there any reason we can't just create them lazily in WriteCommon(), if we actually need one?   (We add the WYCIWYG channel to the loadgroup when we create it--but we could do that during lazy creation too, right?  I don't see any other complications)

Note that under e10s simply creating a WYCIWYG channel also creates an IPDL channel, which then creates another WYCIWYG channel in chrome.  And then we have to destroy it and the IPDL channel later on.   Lots of effort for nothing.

Never mind--I misunderstood when OpenCommon gets called.  D'oh!
