Message:
I consider this not a bug but a feature request since no output is lost
(it's only buffered, when you exit mclient or close the output file, the
data *is* flushed first).
A possible work around is to direct output back to stdout before looking
at the output file (however, there is no way to then continue outputting to
the file).
Despite this not (IMHO) being a bug, I have fixed it (in the stable
branch) by adding a fflush just before a new line is read from stdin.

Message:
Thanks! Confirmed. I hope fflush could be implemented after each query.

Message:
I have run to that before. Since you are outputting to a file, the buffer
is not flushed, so either you wait for a while or you exit mclient to force
flushing. This is not the correct way to deal with the problem of course, I
am just pointing out the problem and a work around.
