+380: Accessor redefinition fails because of old accessor name
+  When redefining an accessor, SB-PCL::FIX-SLOT-ACCESSORS may try to
+  find the generic function named by the old accessor name using
+  ENSURE-GENERIC-FUNCTION and then remove the old accessor's method in
+  the GF. If the old name does not name a function, or if the old name
+  does not name a generic function, no attempt to find the GF or remove
+  any methods is made.
+
+  However, if an unrelated GF with an incompatible lambda list exists,
+  the class redefinition will fail when SB-PCL::REMOVE-READER-METHOD
+  tries to find and remove a method with an incompatible lambda list
+  from the unrelated generic function.

+381: incautious calls to EQUAL in fasl dumping
+  Compiling 
+    (frob #(#1=(a #1#)))
+    (frob #(#1=(b #1#)))
+    (frob #(#1=(a #1#)))
+  in sbcl-0.9.0 causes CONTROL-STACK-EXHAUSTED. My (WHN) impression 
+  is that this follows from the use of (MAKE-HASH-TABLE :TEST 'EQUAL)
+  to detect sharing, in which case fixing it might require either 
+  getting less ambitious about detecting shared list structure, or 
+  implementing the moral equivalent of EQUAL hash tables in a 
+  cycle-tolerant way.
