Define thread safe.

It's safe in the way that the buffers each call to send will have 
will be what you expect.

Ex.

thread1 sends [1,2,3] and thread2 sends [4,5,6]

then you're guaranteed that what you receive would be [1,2,3] and 
[4,5,6].

What it isn't safe from would be race conditions.

So you don't know if you get it like [1,2,3,4,5,6] or 
[4,5,6,1,2,3].

So if the order of the buffer matters then you should use a 
mutex, but if the order doesn't matter then you don't need to.
