When a client connects with follow=1 and then disconnects we can get stuck in sd_journal_wait indefinitely if no journal messages are logged. Every time a client does this another thread is allocated and these continue to stack until either a journal message is logged or we run out of mapping to put a stack in. By adding a timeout if we don't see any journal messages in that timeout we will simply pop back out to microhttpd which will sanity check the connection for us and if it is still connected pop us back into the wait for more journal messages.
