Your diagnostic work is helpful:  rsync calls a recursive function for every
level downward in the directory hierarchy, so you need enough stack to be able
to descend low enough to the deepest subdir.  The one thing that makes the stack
memory use so large is that rsync is currently allocating a filename buffer on
the stack for every level of directory descent.  I'll check to see if this
would
be easy to optimize that.

The latest CVS source (also available in the latest "nightly" tar
file) now uses
a lot less memory for each level of directory recursion -- I eliminated the need
for the MAXPATHLEN buffer, and replaced it with 3 small variables (typically 12
bytes or so).
