[Xorp-hackers] Crash due to stale cached xrl sender pointer.

[Bruce Simpson]

I wonder here if we're better off just making the per-method cached Xrl 
a property of the XrlFooClient stub class itself. This would also fix a 
memory leak while we're at it, but means modifying the clnt-gen code 
generator.

I believe you hit the problem with your multiple instance patch in the 
tree; perhaps if the re-entrancy problem in the libfooxif.so stubs is 
eliminated, your stuff will work w/o the ref_ptr patch.
