Not all accept() errors are properly handled.
Some of the errors should be marked as non-fatal, for example:

#### Linux, BSD, MacOS systems:

* `ECONNABORTED` should be handled in `chronos`.
* `EMFILE`, `ENFILE`, `ENOBUFS`, `ENOMEM` could be treated as `TransportTooManyError` (which is not fatal).
* `EBADF`, `EINVAL`, `ENOTSOCK`, `EOPNOTSUPP`, `EPROTO`, `EFAULT` (BSD MACOS) could be treated as fatal.

#### Windows
* `WSAECONNABORTED` should be handled in `chronos`. (treat it as ECONNABORTED on *nix).
* `WSAEMFILE`, `WSAENOBUFS`, `WSAETOOMANYREFS` - `TransportTooManyError`.
