Consider adding configuration options for blocking executor to ExecutorModule #593
Description
It would be useful to have the option to configure coreSize and keepAlive values in ThreadPoolExecutorConfig passed to the blocking executor during its creation via ExecutorModule make methods.
Since by default the coreSize is set to 0 and the keepAlive to 1000 millis, there might be a large number of blocking threads created and closed if a program schedules repeated task to blocking executor with interval higher than the keepAlive.
It would be nice to add these parameters to the existing methods with default values set to the current value either directly or wrapped in the ThreadPoolExecutorConfig.
