# 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.
