* test/io/wait/test_io_wait.rb (test_wait_readwrite_timeout):
select(2) in AIX returns "readable" for the write-side fd of a pipe, so it is not possible to use a pipe to test the read-write timeout of IO#wait on AIX. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54047 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
