Actually, hundreds were when I tried to use buffer-local ispell-process because then ispell-internal-change-dictionary didn't kill ispell-process but ispell-init-process created new processes. But with the default configuration there are "only" a dozen of processes. I guess one process per buffer. And this is even in case when ispell-process is NOT buffer-local. I noticed that all these processes are created after loading the desktop buffers. > And why are you saying "almost on every key press"? are different > personal dictionaries defined for different portions of text in some > way? Otherwise, I'd expect hunspell to be restarted when you change > buffers, whuch is hardly "on every key press". Or what am I missing? On every key press was only when trying to use buffer-local ispell-process. But with the default configuration ispell-process is killed and started "only" on switching buffers that is very annoying since most of the time I see these messages in the echo area: Ispell process killed Starting new Ispell process /usr/bin/hunspell ... Ispell process killed Starting new Ispell process /usr/bin/hunspell ... Ispell process killed Starting new Ispell process /usr/bin/hunspell ... ... >> Is it possible to fix this? > > Not easily, AFAIR. But I don't think I understand the nature of the > problem you are experiencing, see above. The nature of the problem is the inability of ispell.el to maintain multiple processes with different dictionaries simultaneously that is required by flyspell-mode. What is needed here is a hash of processes where the key is the ispell program name and its dictionary arguments.
