Description
when operating as a server and using listeners, if the number of open FDs is equal to the limit on FDs, accept will return an error and the driver will spin at 100% cpu until an FD is freed up for the incoming connection.
Suggested fix:
If "accept" returns a "too many open files" error (ENFILE or EMFILE), the listening socket should be taken out of the read-fds for a time (say one second) before retrying.
If this is not practical to do in Proton, the driver should provide hooks for the encapsulating application to use to provide this holdoff.
