Looking at these values these seems to be a bit bogus, the alarm
prototype is defined with unsigned int, so the only value that makes
sense here would he UINT_MAX.

The -1 == ULONG_MAX when converted to unsigned int and ULONG_MAX + 1
would end up as 0.

Also alarm() returns the number of seconds remaining for the alarm, so
we should really do something as:

* call alarm(UINT_MAX);
* check the return value was 0
* call alarm(0);
* check that the return value was either UINT_MAX or UINT_MAX - 1
