Please Note:
- The IVSHMEM driver has a hard limit of 32 events.
- Events that are singleShot are released after they have been set.
- At this time repeating events are only released when the driver device
handle is closed, closing the event handle doesn't release it from the
drivers list. While this won't cause a problem in the driver, it will
cause you to run out of event slots.
