Great, glad to hear it's been stable for you.

Yes, that's expected, due to two reasons:
* I did not do much work on optimizing this code yet, there's debug statements
in etc. I will take care about that soon.
* Eventually, fso-abyss should not run as an own process doing the "forward
virtual serial lines over pty" thing to ppp, but rather as a library handling
the data from the virtual serial lines directly. This would reduce a bunch of
turnarounds and copies. It's a lot more work to make this happen though.
Ideally, we'd have multiplexing in kernel, of course...
Thanks for testing!
