One of the reasons this has not previous been implemented is that the order in which find examines the file system is only partly defined (i.e. start points are examined in order, either depth-first or in preorder).   Hence using a limit of say 100 would provide almost no control over which 100 results are generated.

A second reason is that there is ambiguity over what a "result" is.  Consider this for example:

find / -name foo -fprint /tmp/foos  , -name bar -fprint /tmp/bars -max_count 200

What behaviour should one expect?

The -quit predicate suffers a bit from the first problem but not when the second (since it takes effect as soon as it is reached).
