UI blocks every keystrokes on larger files (main thread waits for presentation compiler)

Every time I stop typing in a larger file (1500 lines, for instance), the UI becomes unresponsive for a few seconds. It turns out the main thread blocks waiting for the Java Reconciler thread, which in turn waits for a response from the presentation compiler. It would be better if the reconciler and the UI thread didn't synchronize on the same lock object (they both use the document lock), or try to delay locking the document until the response from the presentation compiler is ready. I set the priority to high because I think this is a real problem for adoption, although I don't know what's the policy for assigning priorities to tickets.

The most straightforward fix here would be to make a temporary copy of the underlying source file buffer so that the presentation compiler can consume the contents without having to hold the buffer lock.
