- # 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.
