It looks good. I see only a few issues.

Space before parenthesis (and elsewhere in the patch).

RealTimeSignum tests should be moved into a
class/Mono.Posix/Test/Mono.Unix.Native/RealTimeSignum.cs file.

CreateWaitSignalThread() would be a better name.

You need to ensure that the UnixSignal is disposed, as WaitSignal()
won't (and can't). (The UnixSignal must be disposed so that it will
unregister itself, otherwise subsequent tests may fail.) Thus, this
would be better done as:
RealTimeSignum rts = new RealTimeSignum ();
using (UnixSignal signal = new UnixSignal (rts)) {
Thread t1 = CreateWaitSignalThread (signal, 5000);
Thread t2 = ...;
}
Alternatively, make CreateWaitSignalThread() higher-level, e.g.
static void MultiThreadTest (UnixSignal signal, int timeout,
ThreadStart b)
{
Thread t1 = CreateWaitSignalThread (signal, timeout);
Thread t2 = new Thread (b);
t1.Start ();
t2.Start ();
t1.Join ();
t2.Join ();
}
with a caller of:
RealTimeSignum rts = new RealTimeSignum ();
using (UnixSignal signal = new UnixSignal (rts)) {
MultiThreadTest (signal, 5000, delegate () {
Thread.Sleep (1000);
Stdlib.raise (rts);
});
}

This type should be moved into Mono.Unix.Native, so that it's in the
same namespace as Signum.

There's no need to call UnixSignal.GetSIGRTMAX() here, as the MaxValue
field has already computed this. Just do:
if (offset > MaxValue.Offset)
throw new ArgumentOutOfRangeException(...);

This should delegate to Equals(RealTimeSignum) so that the core logic
isn't duplicated.

This property should be closer to the constructor, before Equals() and
the overridden operators.
