Fixing this properly will be ugly. What happens is a method is invoked
using MethodInfo.Invoke (). To implement this, the runtime constructs a 
runtime-invoke wrapper. These wrappers are shared to avoid creating too many of
them. They are shared based on signature, and if the method has generic
as arguments, those instances become part of the signature. When a generic
instance is freed, we would need to scan all wrappers to determine whenever
reference this instance, and free those too. This would be very slow,
since the wrappers are grouped on a per-image basis, so there is no central
table we can check.

In this concrete case, the situation is easier, since instead of the signature,
the class where the wrapper is placed in is a generic instance. This could be
fixed easily, but the general problem is hard to fix.
