+####################################################
+# glibc-2.X specific
+# These are generic cover-alls which catch a lot of stuff
+# in various combinations of ld, libc and libpthread
+#
+# Note this is heavyhanded and not very clever:
+#
+# - suppress anything that has its top frame in ld.so
+#   That's fine, since it's mostly dynamic linking stuff,
+#   which has various deliberate (harmless) races
+#
+# - suppress anything that has its top frame in libc.so.
+#   This really isn't clever, since it could hide some 
+#   legitimate races.  But the problem is, if we don't do
+#   this, then loads of errors to do with stdio are reported, because
+#   H fails to see glibc's internal locking/unlocking of FILE*s
+#   as required by POSIX.  A better solution is needed.

+# These are very ugly.  They are needed to suppress errors inside (eg)
+# NPTL's pthread_cond_signal.  Why only one stack frame -- at least we
+# should see the wrapper calling the real functions, right?
+# Unfortunately, no: the real functions are handwritten assembly (in
+# the glibc-2.5 sources) and does not create a proper stack frame.
+# Therefore it's only one level of unwinding before we're back out in
+# user code rather than the 2 levels you'd expect.
