That's not supposed to be happening.  (Several static and global variables 
got removed (and moved instead to "UsageEnvironment"-specific state) a few 
months ago, but it's conceivable that there are some remaining variables 
that might cause a problem.)

You could well be right; I'll look into this.  In the meantime, you could 
try putting a mutex around that code.

That's always an option :-)
