Implementation of a new Resource Sharing Protocol

[Malte Münch]

Hello,

now i've read through a bit of code. Isn't _Thread_queue_Operations_FIFO
respectively _Thread_queue_Do_nothing_priority_actions more suitable for
me than _Thread_queue_Operations_priority with priority_actions
_Thread_queue_Priority_priority_actions?

Best regards

Malte
