"type ahead" bug with cygwin

Robert Body
Hi, I found something that I think is a fundamental issue with cygwin.

During an ftp session, when the shell was tied up for 15 minutes, I typed
something, and of course it was echoed, but when the ftp session completed,
the commands I typed were lost, no action was taken.

Of course a real linux/unix system would have carried out those actions
after completing the ftp.

This wasn't just a one command ftp call, it was an ftp call in a script
called by another script, but I think this would happen if i just did ftp
command from the command line.

Mmm, are you sure?

There is a little bug indeed, in that they aren't echoed on the next
prompt, but if you type one character more, you'll see all of them (the
previously typed and the one just typed) appear.

Regards,
Samuel

Yes Samuel, I am sure, I just tried it now, and it's been a couple of Cygwin
restarts since last time.

I type a command "g geo" which runs 3 scripts deep to accomplish TGZipping,
FTPing and then SSHing as part of file upload process. During that time
(which happens during FTPing, the longest process) i type another command "g
answers" <enter>

When "g geo" completes I even press <enter> (again), but nothing is present
to take action, my up-key history confirms that indeed "g answers" never
registered as a command, even though it echoed as I originally typed.

It could be the 3 levels deep script mechanism that's losing the input, but
i believe that a regular Unix/Linux would keep the info present and execute
the new command upon first one's completion.

This is not the first time it happened, it's 100% consistent to fail.
