Description

The number of threads in IPCLoggerChannel#createParallelExecutor is elastic right now, make it fixed.
Presently the corePoolSize is set to 1 and maximumPoolSize is set to numThread, but since the size of Queue is Integer.MAX, the queue doesn't tend to get full and threads are always confined to 1 irrespective of numThreads
