摘要：A technique for efficiently boosting the priority of a preemptable data reader in

order to eliminate impediments to grace period processing that defers the destruction

of one or more shared data elements that may be referenced by the reader until the

reader is no longer capable of referencing the data elements. Upon the reader being

subject to preemption or blocking, it is determined whether the reader is in a read-side

critical section referencing any of the shared data elements. If it is, the reader's priority is

boosted in order to expedite completion of the critical section. The reader's priority is

subsequently decreased after the critical section has completed. In this way, delays in

grace period processing due to reader preemption within the critical section, which can

result in an out-of-memory condition, can be minimized efficiently with minimal

processing overhead
