Comment(by joeyadams):

 What if readRawBufferPtr simply called threadWaitRead before making the
 safe foreign call?  I suppose there's a theoretical risk the foreign call
 may block after that, but it seems far less likely after a successful
 return from threadWaitRead.

 Does threadWaitRead work on Windows with -threaded ?
