Yeah, but it's fine though because 10000 / 256 fits into int without a
problem.

I'm not sure this sort of patch is worth it when it's just a style
debate instead of a bugfix.  I'm a little bit torn about this.  In
Smatch, I run into this issue one in a while where Smatch doesn't know
if the timeout is less than int.  Right now I hacked the DB to say that
these functions always return < INT_MAX.

Anyway, for sure the commit message should say that it's just a cleanup
and not a bugfix.
