 The Spirolaterals activity should ask OLPC Fedora-based builds not to
 suspend while its drawing routine is active.

 Since it takes more than 15 seconds to complete a drawing cycle based on
 many user-entered patterns, and drawing is done in a step/pause/step
 manner which doesn't use much CPU, a XO laptop can decide to suspend
 before the completed image is drawn.

 This can be done by created a PID-based flag file when the playback
 routine is started, and removing said file when drawing is stopped or
 completed.

 Seen with Spirolaterals-23 & OLPC OS 11.3.1 os31 on XO-1.5.
