   This shows, IMHO, the need for a -R flag for grep, something which
   I've felt wanting many times.

So far, I haven't seen anyone suggest the following:

   grep '^limfree' `find /usr/src/sys -name '*.c' -print `

Is there some reason why this is worse than using a construct like 
find | xargs | grep ?
