Tightened Threading Semantics
•A PERC thread honors the priority specified by the developer
–Priorities are never automatically “aged”
•Every PERC synchronization lock implements priority inheritance
•All lock and wait queues are maintained in priority order
•Optional use of extended priority range (1-32)
•These semantics are offered across all targeted operating systems: ETS, INTEGRITY, Linux, LynxOS, Nucleus, OSE, RTX, VxWorks, WinCE, Windows, QNX
