Thanks for the feedback. Keep in mind that the feature is still being
developed. Some things may just be missing. But there can also be bugs
and things that don't work for you, so feedback is useful anyway.

It's normal for a process to have some initialization time before the
socket is ready for use. This is implemented, it already existed for
netbeans. Did you add a "waittime" argument? The default is zero.

If you are using raw messages Vim has no clue where a message ends and
whether there is more coming. Vim should get the second message, but
possibly only in the next read. If it never arrives there can be a bug.
I just fixed one where raw messages were dropped when there is no
handler.
I just added the ch_logfile() function, that will be useful to find out
what is happening.
