latch levels and latch deadlock

Hello,

I've some questions:

• If higher level latch is requiested in willing-to-wait mode while holding lower level latch, will process sleep whether or not this higher level latch is available ?
• how does process continue its processing in no-wait mode ? what is the mechanism ? to prevent from latch deadlock, how does process release its holding higher level latches ? is there a latch recovery ?

regards...
