> This patch releases the InvokeMethodTable_lock while creating a method handle intrinsic.  If there's a race, it frees a Method created by racing thread.  The logic is simple but uses the deallocate_list infrastructure that's mostly used for redefinition making it less rare.  With Dacapo2009, this adds about 20 Methods + constant pools to the list.  Also the method has to call nmethod->flush which is assumed to be something only GC calls.
