I make this problem go away just by increasing ttyhog without touching
ibufsize; this is why I don't think there is any interrupt latency problem;
I tried increasing ttyhog instead of RS_IBUFSIZE. It looses less
characters (but it still looses sometimes). But the random load-related
reboots did not disappear. I'll go try increasing both RS_IBUFSIZE and
TTHOG next.
