[Mono-list] Interlocked on a SMP machine

I have some code that is implemented two ways. Once using a standard
lock, and once using System.Threading.Interlocked and no locks
Both seem to function correctly, however, the Interlocked version
seems to only use one CPU (my max CPU is 100%). When using the lock
based version, the CPU utilization goes to 200% (approximately).
Thus, the lock version is much faster.
Is this to be expected? Have I misunderstood Interlocked? Is it a
limitation in mono?
This was on mono 1.2.3 from Ubuntu 7.04.
