Isn't this a dangerous thing to do even on non-function-descriptor
architectures?  If I understand you right, GCL depends on the loader
mapping the shared objects on subsequent executions at the exact same
location as during the original execution.  Wouldn't, e.g.,
LD_PRELOADing something break this assumption?
