There is a problem with reusing numbers - it is probably only a small one - but
it might be larger than the problem of running out of unit IDs:
The user might reuse NEWUNIT= IDs:
Open(newunit=id)
...
close(id)
open(unit=id) ...
The latter is illegal as one may only pass positive numbers to unit=, but I
would not count on it. Given that the number is huge, we decided that the
current method of just incrementing the value should be sufficient for nearly
all cases and one can think about something clever if a real-space code
encounters the problem. However, I don't mind if one solves the problem before.
