king: fix typo in UDP.hs comment
1. Opens a UDP socket and makes sure that it stays open.
- If can't open the port, wait and try again repeatedly.
- - If there is an error reading or writting from the open socket,
+ - If there is an error reading to or writing from the open socket,
close it and open another, making sure, however, to reuse the
same port
NOTE: It's not clear what, if anything, closing and reopening
