[Swan-dev] xauth_send_request has a comment that confuses me

It does the following:

- performs everything on the main thread, but but wait there's more

- right at the very end create of an xauth thread who's only task is to
schedule an event to report back that things passed/failed

while horrible it was easier than figuring out how to get the IKEv1 and/or
event code so that things only sometimes suspended

(clearly the thread bit in the middle is just a tad excessive :-)

ah, I missed that one
