Using HttpWebRequest asynchronously with HTTPS

...seems to have a serious bug when building and running in DEBUG.

Works fine in release (go figure), but in DEBUG the HttpWebRequest will not actually connect but instead hang until the remote server closes the connection due to timing out.

Anybody else ever run into this?

There's a bugzilla entry for "weirdness using HttpWebRequest under DEBUG" for Mono (or Xamarin, I can't remember.)

Some people claim this bug was fixed in Mono, but that Unity is using a very old version of mono but I can see related bugs in their tracker...
