I've seen it mentioned that "uv_close is not thread safe". I'm experienced with writing multi-threaded C/C++ code, but I'm still not sure what is being said here.
Does this mean that uv_close must always be called in the main thread?
Or, is this simply warning that uv_close must not be called in parallel to other uses of the handle (seems obvious..)?
I'm dealing with an uv_async_t handle, if that's relevant...
Per the discussion here:
https://github.com/libuv/libuv/issues/709
uv_close may not be called outside of the loop thread. In addition, it should be mentioned that no libuv functions, aside from uv_async_send, are safe to call outside of the loop thread.
