NAME

       AnyEvent::AggressiveIdle - Aggressive idle processes for AnyEvent.

SYNOPSIS

           use AnyEvent::AggressiveIdle qw(aggressive_idle};

           aggressive_idle {
               ... do something important
           };

           my $idle;
           $idle = aggressive_idle {
               ... do something important

               if (FINISH) {
                   undef $idle;    # do not call the sub anymore
               }
           };

DESCRIPTION

       Sometimes You need to do something that takes much time but can be split into elementary
       phases. If You use AE::idle and Your program is a highload project, idle process can be
       delayed for much time (second, hour, day, etc). aggressive_idle will be called for each
       AnyEvent loop cycle. So You can be sure that Your idle process will continue.

EXPORTS

   aggressive_idle
       Register Your function as aggressive idle watcher. If it is called in VOID context, the
       watcher wont be deinstalled. Be carrefully.

       In NON_VOID context the function returns a guard.  Hold the guard until You want to cancel
       idle process.

   stop_aggressive_idle
       You can use the function to stop idle process. The function receives idle process PID that
       can be received in idle callback (the first argument).

       Example:

           use AnyEvent::AggressiveIdle ':all'; # or:
           use AnyEvent::AggressiveIdle qw(aggressive_idle stop_aggressive_idle);

           aggressive_idle {
               my ($pid) = @_;
               ....

               stop_aggressive_idle $pid;
           }

       The function will throw an exception if invalid PID is received.

Continuous process.

       Sometimes You need to to something continuous inside idle callback. If You want to stop
       idle calls until You have done Your work, You can hold guard inside Your process:

           aggressive_idle {
               my ($pid, $guard) = @_;
               my $timer;
               $timer = AE::timer 0.5, 0 => sub {
                   undef $timer;
                   undef $guard;   # POINT 1
               }
           }

       Until 'POINT 1' aggressive_idle won't call its callback.  Feel free to
       stop_aggressive_idle before free the guard.
