125 will be not always but only to avoid returning -1 (or any negative).
There is no practice to exit with errno, AFAIK. Plus, errno we have at
the end (and which is reported to user) frequently is bogus and that
should be fixed. (I may do this later maybe, don't know how much work
that would require).
We also wish to reserve some exit code as hard error for tests.
