There has been a statement of

"The timeout() call is the old style and new code should use the
     callout_*() functions."

in timeout(9) since 2003.  I reworded this to be more strong about 3 months 
ago:

LEGACY API
     The functions below are a legacy API that will be removed in a future
     release.  New code should not use these routines.

This did not make 10.1 AFAIK, but will make all later releases before 11.0 
hits.  Note that timeout(9) is always Giant-locked, so there is extra impetus 
to not use it.
