Correct is that they're asynchronous to each other. But mutexes aren't
used to switch between them. Mutexes are used to lock-out any other
thready while accessing commonly-used resources.

For example, if you have an application that echoes everything back, you
probably don't need *any* mutexes at all, because receiving one byte and
sending it back doesn't access any commonly used resources.

They are independant. If you need "synchronous" working mode, you
probably shouldn't use threads at all:-)

Maybe first start with an exact description of what needs to be done. To
speak honest (and not offending), parts of your sources looked quite
spaghetti-like (but that may be because of cutting out any unneeded
code). So maybe a description of the exact task would be a better start
here...
