The multitasking schema is restrictive due to the fact that power and performance considerations for a mobile device stacks the multitasking prioritization appropriately. An iOS device isn't a desktop machine with continuous power on from an external source, nor do they have the nearly infinite memory capacity of modern desktop systems ... ;-) But it works very nicely for what it was designed to do. It wasn't designed to be a multi-user unix server, after all. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
