Comment (by justin):
"4095" is reasonable as a magic number, but I'm concerned that it's more
random than magic in this case :-}
Since we have a failure at precisely 4095 (or 6), I think we should err on
the side of caution here: there's no direct evidence (from looking at the
kernel source for Mac OS X) that 4095+/- 1 is magic, so we could trip over
this later with a smaller value (3071 for example). Linux may have
similar limits, but not necessarily the same ones; their tty code differs.
As I noted above, dropping characters (which is what's being done here)
can occur when this limit is hit, or for other "resource-limit" issues,
and it's hard to predict what the number is in those cases.
