The handling of relative paths has changed between versions 3.6 and 4.0. 
  It may be that you are running into a specific exception (or used to 
take advantage of an exception).  If you consider this to be a bug you 
could file it in bugzilla with a sample mapfile and a description of 
your installed directory structure (i.e. where the mapfile is located, 
where you expect ../tmp to be located, etc.) and we could investigate.

Because the WMS server doesn't need to write to the IMAGEPATH directory, 
but the WMS client does.

The WMS client writes the temporary images that it downloads from the 
remote WMS server in the IMAGEPATH directory and deletes them as soon as 
it's done with them.  So you never see any files in the IMAGEPATH 
directory in this case but it is being used.
