Thanks, this is now in with a few modifications.  I added some basic
documentation to the top of the header file, which is in as inn/timer.h
instead of timer.h (down the road, when we install libinn, we'll want to
install this header file).  I removed the gethrtime call in favor of just
using gettimeofday, and while I really like the idea of using alloca, I
don't think we're ready for it and I went back to straight xmalloc.  Down
the road, though, we should seriously look at putting the infrastructure
in place to use alloca.  I can think of a bunch of stuff in INN that would
benefit from it.
