LibreOffice core uses that, too, and we support an even more
restricted set of compilers.

It is useful to find all uses of TerminationFlag directly with git
grep without having to look through abstractions.

It's not easy, it can interfere the tile tracking.

When switching parts (either by the keyboard or mouse)
LoKit sends a notification of the current part and
invalidates tiles. As a reaction to that the client
cancels its tiles and requests new tiles for the
new part.
Since the response to setpart is a large number
of tile cancellation and new requests, the
cost of setpart is significant (esp. with large
number of clients). To avoid that, we de-duplicate
setpart entries from the client queues so there
would be only at most one setpart (the last)
queued to be sent to the client. This minimizes
the unnecessary noise when the part changes
faster than the server and/or network can
keep up.

While message emplacement happens in the DocumentBroker poll, we
can be sure that the next iteration of the poll will call
hasQueuedWrites before polling.
To avoid degrading performance for everyone
because of a single slow/bad connection, we
send data to clients each in its own thread.

The pool is checked for expansion before processing
items from the queue. By tracking the number of idle
thread (i.e. not currently sending data) we ensure
that there is at least one idle thread before
we invoke the socket.
If there is not enough idle threads at that point,
a new thread is spawned, so long as we're below the
limit. This guarantees that even if all the active
threads block on the socket, we'd always have one
more to process new data (until we reach the limit,
which is as many client connections as we have).
Technically, a single slow connection could
still monopolize all connections if there are
many messages to be sent to it. For that we'd
need to track and assign one thread per connection,
something we don't currently do.
