Thread safe Mono

[volodya-lombrozo]

During solving the eo issue we faced with the concurrency problem. The problem in MnCsv - it's not a thread safe class. I suggest to implement something like ThreadSafeMono which will make read/write locks for both methods. In other words, we need a thread safe implementation of Mono as a decorator for other Mono classes.

@volodya-lombrozo @yegor256 can i help you here? if so, does it make sense to make read() method locked?

[yegor256]

@l3r8yJ sure, go ahead. Would be nice to have MnSynchronized decorator of Mono, I believe

[volodya-lombrozo]

@l3r8yJ I think it makes sense. Otherwise you can read() some garbadge if another thread will be in the middle of the write(), in some cases you can get even an exception. The actuall behaviour will depend on decorated object.

@volodya-lombrozo see your point
