We have witnessed a regression (or at least a semantic change) of 
20030502 wrt 20030312 : the behaviour in -basis 1997 mode differs in the 
following scenario:

    1) start a server which listen on a socket;
    2) accept a connection;
    3) apply canInput on the corresponding instream.

The newer MLton does not seem to wait, and the corresponding canInput 
says that nothing is available, with errno=11, as if the instream 
generated from the accept() call had been opened in nonblocking mode. 
Looking at the cvs diffs, I was wondering if it could arise from the 
activation of the new IO.

Thanks for your help.
