IO-Async 0.60_001

on Perl CPAN

• Some OSes lack signals; forbid the ->*_signal methods, and use
  waitpid() polling for child processes if so
  
• Rearrangement of $loop->listen and IO::Async::Listener logic to
  allow Listener subclasses to use listen extensions (e.g. SSL)
  
• Allow ->listen to construct new Stream or Socket handles
  
• Updated documentation and tests to emphasise futures with resolver
  and ->listen
  

Note: These changes break IO::Async::SSL versions 0.12 or older.

[BUGFIXES]

• Ensure that $stream->write( CODE, on_write/write_len ) works
  correctly
