> After performing an upload File Transfer, plugins no longer work.  What I _think_ happens is that if there are plugin interfaces during file transfer, for example, a console.log or File process, the first one triggers the _execXhr_ command with _gap_exec_ keyword, but this is not picked up.  That is, it does not result in a CDVURLProtocol:canInitWithRequest.  But the command is in the javascript commandQueue.  No additional commands will trigger an execXhr b/c of the logic that assumes that if the command queue length > 1 the native side has already been "poked" and will pick up the commands shortly.  If the native side has lost the command (and I don't know how or why), we're now wedged.  A quick hack to prove the issue is to retrigger the execXhr if the command queue length is > 5, for example.  This causes the native side to be poked again, and things work again.
