Yes, I agree. At 38k4 you need 130 ms to fill the flip buffer. And if
you see this kind of delays there is something "wrong". An easy
solution like increasing the buffer size may delay the fenomenon to
the point that it is hard to reproduce, but we haven't really fixed
anything. In some cases not receiving any chars for 130 ms can be
annoying too....

And at 115kbaud you need 44ms to fill the flip buffer. So you'd have to
miss 4 clock ticks before the flip buffer would be overflowing. I can
believe we're missing 1, or maybe even 2, but 4?
