  35 # maybe_threads.cc was written to allow LD_PRELOAD=libtcmalloc.so to
  36 # work even on binaries that were not linked with pthreads.  This
  37 # unittest tests that, by running low_level_alloc_unittest with an
  38 # LD_PRELOAD.  (low_level_alloc_unittest was chosen because it doesn't
  39 # link in tcmalloc.)
  40 #
  41 # We assume all the .so files are in the same directory as both
  42 # addressmap_unittest and profiler1_unittest.  The reason we need
  43 # profiler1_unittest is because it's instrumented to show the directory
  44 # it's "really" in when run without any args.  In practice this will either
  45 # be BINDIR, or, when using libtool, BINDIR/.lib.
  46
  47 # We expect BINDIR to be set in the environment.
  48 # If not, we set them to some reasonable values.
