It was never intended to be public, only as a debugging aid for assertions. :(  
I had hoped that the calling code would know when it was in an ithread or not 
and call different routines as needed (i.e. that the programmer would 
intentionally think about the context they were in).  Perhaps this is not 
realistic?  Are you really queueing new I/O from ithreads and/or timers?
