	reduced (ROOM T) functionality down to just (ROOM),
		since (ROOM T) is flaky on my machine again and
		I don't know how to fix it
	logged the problem in BUGS

+344: more (?) ROOM T problems (possibly part of bug 108)
+  In sbcl-0.8.12.51, and off and on leading up to it, the
+  SB!VM:MEMORY-USAGE operations in ROOM T caused 
+       unhandled condition (of type SB-INT:BUG):
+           failed AVER: "(SAP= CURRENT END)"
+  Several clever people have taken a shot at this without fixing
+  it; this time around (before sbcl-0.8.13 release) I (WHN) just
+  commented out the SB!VM:MEMORY-USAGE calls until someone figures
+  out how to make them work reliably with the rest of the GC.

     bug #79)
+  * bug workaround: ROOM T and the GC were not working together
+    reliably, because invariants expected by the SB!VM:INSTANCE-USAGE
+    reporting facility aren't preserved. That reporting has been
+    disabled, so now until and unless someone figures out how to make it

   * minor incompatible change: as threatened around sbcl-0.8.0, the
     home package of MOP-related symbols is now SB-MOP, not SB-PCL.
     The symbols are also exported from SB-PCL for backwards
