I think this is a satisfactory short term (or even mid term) solution.
I think the long term solution will be to introduce a method for adding
offsets to CORE_ADDRs.  See

    http://sources.redhat.com/ml/gdb/2001-10/msg00036.html

I think it's okay to commit this patch, but I'd appreciate it if you'd
add a comment indicating that svr4_truncate_ptr() should be removed
when methods for adding displacements to CORE_ADDRs are introduced.
