=head1 NAME

ZeroMQ::Context - A 0MQ Context object

=head1 SYNOPSIS

  use ZeroMQ qw/:all/;
  
  my $cxt = ZeroMQ::Context->new;
  my $sock = ZeroMQ::Socket->new($cxt, ZMQ_REP);

=head1 DESCRIPTION

Before opening any 0MQ Sockets, the caller must initialise
a 0MQ context.

=head1 METHODS

=head2 new

Creates a new C<ZeroMQ::Context>.

Optional arguments: The number of io threads to use. Defaults to 1.

=head1 CAVEATS

While in principle, C<ZeroMQ::Context> objects are thread-safe,
they are currently not cloned when a new Perl ithread is spawned.
The variables in the new thread that contained the context in
the parent thread will be a scalar reference to C<undef>
in the new thread. This could be fixed with better control
over the destructor calls.
