Seems very high for a HA-System. On the other hand maybe someone wants
the system to wait for a whole weekend.
3 days = 259200 seconds. I would like an easier to remember plain value
like 100000, 200000 or 300000.

Very easy explanation:
As we all know, usally numbers represented in text are converted to an
easier to handle representation inside a program. This can be hex,
decimal packed, floating etc. and mostly will be of fixed length. Even
bignums will have an upper limit (e.g. 64Kdigits). If there is no check
for a maximum value at input, funny things can happen in program logik
afterwards: overruns, skip to negative values, truncated values, which
possible could cause crazy program behaviour.
I do not aspect many of these errors, as the bug rate of drbd is very
low (congratulations!) and at minor level.

Yeah. But it needs a minimum of cooperation from developers. E.g. such
messages like "solved, ready for retest", "won't solve", priorities etc.
