/* We have two sides which can lock our vmutexes:
 *  1st side uses acquire/release functions and it can only hold mutex when
 *    `counter` is zero. If counter is not zero `acquire` waits.
 *  2nd side uses increment/decrement functions and when it holds mutex it
 *    increments `counter`. This side can't hold mutex while 1st side is already
 *    holding it.
