Ack! Two 5 kB/s streams at once! Your poor kernel!

I think I should remind everyone that receiving at 57.6k can melt
your kernel. Certainly two 57.6k streams at once.

We might bump it to 4k (it's at 2k now), but that'll only help if the
problem's that the kernel gets delayed from dealing with the input.
If the problem's that the kenrel can't keep up, no.

At 57600 baud, it takes 354 ms to overflow a 2k ring buffer. Something
is massively keeping interrupts blocked for way to long (data come out
of the ring at softinterrupt level, which is at about spl 0.5.

I think upping the ring buffer's not the solution, We need to figure out
what's really wrong.

Take care,
