Delayed HTTP conneciton close parameter added
Added close-immediately-on-shutdown logic
Added the ability to fork a Task back onto the same Thread currently running
Removed unwise 'delay http connection close' feature, too many demons buried here even with shutdown cleanup of the framework and platform
Some PMD cleanup
Some PMD issues removed, minor cleanup
add -> addElement typo
Fixes to added Task priority and debug display
More tight shutdown finish- off-by-one meant one other thread might still be finishing up when we notify the platform that app is closed
Better dedicated thread debug, naming of threads
Simpler name for thread
Also cancel the next task when HttpGetter factory of a cache indicates no need to fetch
Examples removed (old version) own copies of libraries; added PicasaViewer Android code example; some documentation to Task
build script, small format
Fixed an off-by-one in how Workers pull items from normal priority q
Removed unused delayed-write from SERIAL priority

Code paths not used related to priority sequence switching and SERIAL
priority were removed. In the process, found some re-sequencing of
prioiries needed. Example: IDLE priority now never runs on the fastlane
Worker and tasks are taken in the intended sequence, always SERIAL before
HIGH or NORMAL
