100% CPU when idling

[danboo]

When I minimize Padre the CPU utilization sits near zero for about 30-45 minutes, but then starts to climb gradually. I would estimate that it climbs about 20 percentage points per hour until it hits 100%.

During this whole time 'perl -d:Trace' shows it repeatedly running the following once per second:

>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:44:                       $self->on_timer( $_[1], $_[2] );
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:87:       my $self  = shift;
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:88:       my $event = shift;
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:89:       my $force = shift;
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:91:       if ( $#{ $self->{queue} } > -1 ) {
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:91:       if ( $#{ $self->{queue} } > -1 ) {
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:111:      $event->Skip(0) if defined $event;
>> /home/danboo/perl5142/lib/site_perl/5.14.2/Padre/Wx/ActionQueue.pm:113:      return 1;

strace shows it repeatedly executing:

It looks like minimizing Padre isn't necessary. Just hiding it behind another window, so it receives no input, is sufficient.
