base: Fix races in IOManager (setNumCapabilities,closeFdWith)wip/21651
Fix for #21651
Fixes three bugs:
- writes to eventManager should be atomic. It is accessed concurrently by ioManagerCapabilitiesChanged and closeFdWith.
- The race in closeFdWith described in the ticket.
- A race in getSystemEventManager where it accesses the 'IOArray' in
'eventManager' before 'ioManagerCapabilitiesChanged' has written to
'eventManager', causing an Array Index exception. The fix here is to
'yield' and retry.
