Neovim freez when using TabNine

[tzachar]

Hi.

Been using TabNine for a long while.
Lately (neovim nightly), neovim started freezing, mostly when closing or switching buffers.
The main nevom process is hanged on an epoll from the TabNine client, and killing the TabNine process unfreezes everything.

Is this a know issue?
Is there a workaround?

Unfortunately, it is TabNine's problem...

Ok, but I think we can better interact with the process.
Dumping the request as json directly to the process's stdin and directly reading from its stdout is probably not robust.
A better option would be to use non blocking reads, like the attached patch.
I'll report if the patch helps.

Please send the PR. I will test it.

Hm. If edit huge buffer, tabnine process is very busy.
I will add the option for it.
