Not thread safe

[polomsky]

The code is vulnerable to race conditions. Try run with go run -race

One example for all:
broadcast type in adapter.go uses unsynchronized access to the map (Join, Leave, Send)

One way I got it working was to wrap a mutex around calls to BroadcastTo. Another option would be to set up a buffered channel that a worker reads from and emits broadcasts from structs/data in the channel that way it doesn't block senders trying to send broadcasts.

I will try to figure out how to do it right.

I fixed the race condition in broadcast (Join/Send/Leave), but I couldn't find any others running the example app.

Closing this issue because it is very broad. If you have any specific races please open separate tickets for them so it's easier to take a look at.
