# Silent fail here seems the best route since some modules
# may not be available in all environments.
# Since an ImportError may leave a partial module object in
# sys.modules, get rid of that first. Here's what happens if
# you don't: importing pty fails on Windows because pty tries to
# import FCNTL, which doesn't exist. That raises an ImportError,
# caught here. It also leaves a partial pty module in sys.modules.
# So when test_pty is called later, the import of pty succeeds,
# but shouldn't. As a result, test_pty crashes with an
# AttributeError instead of an ImportError, and regrtest interprets
# the latter as a test failure (ImportError is treated as "test
# skipped" -- which is what test_pty should say on Windows).
