=head1 NAME

IOMux::Poll - simplify use of poll()

=head1 INHERITANCE

 IOMux::Poll
   is an IOMux

=head1 SYNOPSIS

  use IOMux::Poll;

  my $mux    = IOMux::Poll->new;
  my $server = IOMux::Service::TCP->new(...);
  $mux->add($server);
  $mux->loop;

=head1 DESCRIPTION

Multiplexer based on the C<poll()> system call, defined by POSIX.

The C<poll> has less administration overhead than the C<select> call
(implemented via L<IOMux::Select|IOMux::Select>) because it avoids the need to play
with bit-vectors to see which file handles got activated. However,
C<poll> is not supported on all platforms.

Poll is only available on UNIX.  Windows Vista has added a WSAPoll with
comparible functionality (probably), but afaik there is no binary wrapper
available for perl yet.
