 ##################### SKIPPED TESTS #####################
 
 # This test checks that we behave properly in an out-of-memory

+# These tests are simply wrong (i.e., they do not test what they intend
+# to test).
+# In particular, these two compare numbers to NaN with != in the current
+# version of the Mozilla tests. This is *fixed* in a later version.
+# The tests should be re-enabled when switching to a new version.

 ##################### SLOW TESTS #####################
 
 # This takes a long time to run (~100 seconds). It should only be run
 # by the really patient.
 js1_5/GC/regress-324278: SLOW
 
 # This takes a long time to run because our indexOf operation is
 # pretty slow - it causes a lot of GCs; see issue
 # #926379. We could consider marking this SKIP because it takes a
 # while to run to completion.
