public <V,T extends Throwable> V call(Callable<V,T> callable) throws T extends Throwable
VirtualChannel
Sends Callable to the remote system, executes it, and returns its result.
Such calls will be considered as user-space requests.
If the channel cannot execute the requests (e.g. when it is being closed),
the operations may be rejected even if the channel is still active.

VirtualChannel
Similar to VirtualChannel.call(Callable) but returns immediately.
The result of the Callable can be obtained through the Future object.
Such calls will be considered as user-space requests.
If the channel cannot execute the requests (e.g. when it is being closed),
the operations may be rejected even if the channel is still active.

The returned reference must be kept if there is ongoing operation on the remote side.
Once it is released, the exported object will be deallocated as well.
Please keep in mind that the object may be also released earlier than expected by JVM
