Does the locking involves in read-char too? My problem is more to
do with read-char. (though there is a speed difference with
write-char, I don't do write-char in the real code.)
At first I suspect that OpenMCL does not do buffering, but then
I saw buffered-stream-mixin.
It may be my system (OSX 10.3 on an ancient G4). Has anyone
notice the difference of read-char speed compared to another
