111.03.00

- Added `Set_lang`, a DSL for sets with constants, union, intersection,
  and difference.
- In `Process`, use `epoll` rather than `select` when possible,

		This prevents errors when selecting on file descriptors numbered
		greater than `FD_SETSIZE` (1024).

- Removed `Syslog` module. There is now `Unix.Syslog` in core instead;
  the APIs are not compatible, but they are similar.
