# This is an internal enum UV_HANDLE_READABLE from uv-common.h, used only by
# handles/pipe.pyx to temporarily workaround a libuv issue libuv/libuv#2058,
# before there is a proper fix in libuv. In short, libuv disallowed feeding a
# write-only pipe to uv_read_start(), which was needed by uvloop to detect a
# broken pipe without having to send anything on the write-only end. We're
# setting UV_HANDLE_READABLE on pipe_t to workaround this limitation
# temporarily, please see also #317.
