# FreeBSD seems to hang on TTOU when running parallel tests # FreeBSD seems to hang on TTOU when running parallel tests
# tested on FreeBSD 11.x # tested on FreeBSD 11.x.

# Solaris gets stuck too, even in non-parallel mode.
# It occurs only in chkbuild. It does not occur when running
# `make test-all` in SSH terminal.
#
# I suspect that it occurs only when having no TTY.
# (Parallel mode runs tests in child processes, so I guess
# they has no TTY.)
# But it does not occur in `make test-all > /dev/null`, so
# there should be an additional factor, I guess.
