# Some systems do not have sub-second file times resolution.
# This is the case for older systems like OSX that uses the HFS+
# file system. HFS+ has a 1 second time resolution. This is a
# problem because the Erlang.mk tests rely on file modification
# times to ensure files were rebuilt. To fix this issue, we
# detect here whether the system supports sub-second resolution,
# and maybe sleep during test execution.
