You need to do that *and* set the interrupt boolean in ThreadContext to 
true for the thread you wish to interrupt.
 
You can do this from Scheme code using thread/interrupt from the 
threading code as well.

Its not that it has its own threads, but rather that Java's interrupt 
only really affects a handful of methods which block.  It doesn't 
actually interrupt most threads.
