I have it spinning up fine, but if I spin up multiple WebKit windows on multiple GUI threads I get alternately segfaults, null returns from WKContextCreate(), and sometimes everything working fine *except right click*. Windows supports having an arbitrary number of message loops running at once, and if I comment out the calls that instantiate webkit windows into my host windows the host windows run fine, so I'm looking to thread-safety in WebKit2 as the culprit. Does it exist?

WebKit2's API is only meant to be used from a single thread. It seems quite likely that your problems are due to making WebKit2 API calls from multiple threads.
