I suspect that making timer resolution smaller can increase overhead
noticeably.

You may be interested to look at
http://hegel.ittc.ukans.edu/projects/utime/

Utime is a kernel patch which seems to make Linux able to dynamically
adjust timer resolution when needed by processes (the normal resolution
is 10ms (for i386)).

Alternatively you may look into RT-Linux.
