Yes, you can consider this a cheap kludge, but if you really need to make a 
segment read-only, then you might consider doing a DosGetCSAlias for it.
This creates a selector (normally considered to runable code) which enforces
the read only property for that segment. You should consider, however, if 
there are any additional repurcussions of doing this that might be prohibitive.

Not knowing what your usage is, this might present an alternative until
OS/2 2.0 comes out with a clean solution.
