Hi,

Just think about it:
You can do it, it's not leagal but how you gurantee that data is sent to
socket in right order ?

For example:

you need to send:
    aaaaaa
    bbbbb

You call aaaaaa from 1 thread and bbbbbb on another:
what may happen:
    aaaaaa
    bbbbb
----- all as you excpect

    bbbbb
    aaaaa
This may happen if bbbbb thread finishes first.

For recieve, you never can be sure what is recieved by one thread and
another.
    may happen following situation:
        aaaaabbb
        bbbb
