Example SSE server in Golang
// v2 of the great example of SSE in go by @ismasan.
// includes fixes:
// * infinite loop ending in panic
// * closing a client twice
// * potentially blocked listen() from closing a connection during multiplex step.

// There seem to be problems with "climatically" and "fezzes" as passwords.
// When using "climatically": Program terminates with "openpgp: unsupported feature: public key version"
// When using "fezzes": Program terminates with "openpgp: invalid data: tag byte does not have MSB set"
// Expected behaviour would be a reinvokation of the prompt function in an endless loop until the right password is used.
