# We only have green select so the options are:
# * leave it be and have selectors that block
# * try to pretend the "bad" selectors don't exist
# * replace all with SelectSelector for the price of possibly different
# performance characteristic and missing fileno() method (if someone
# uses it it'll result in a crash, we may want to implement it in the future)
#
# This module used to follow the third approach but just removing the offending
# selectors is less error prone and less confusing approach.
