+# maybe_threads.cc was written to allow LD_PRELOAD=libtcmalloc.so to
+# work even on binaries that were not linked with pthreads.  This
+# unittest tests that, by running low_level_alloc_unittest with an
+# LD_PRELOAD.  (low_level_alloc_unittest was chosen because it doesn't
+# link in tcmalloc.)
+#
+# We assume all the .so files are in the same directory as both
+# addressmap_unittest and profiler1_unittest.  The reason we need
+# profiler1_unittest is because it's instrumented to show the directory
+# it's "really" in when run without any args.  In practice this will either
+# be BINDIR, or, when using libtool, BINDIR/.lib.
+
+# We expect BINDIR to be set in the environment.
+# If not, we set them to some reasonable values.
