Future-IO 0.22

on Perl CPAN

• Document that you should always poll for at least one of the
  POLLIN, POLLOUT or POLLPRI flags
  
• Provide optional base implementation methods for handling an
  alarm+sleep timer queue, to reduce code duplication
  
• Probe for Future::IO::Impl::KQueue on FreeBSD
  

[BUGFIXES]

• Make sure to actually load the POSIX module to get its constants
  
• Skip over probed impl modules that do not support the poll method
