 #### BOX64_DYNAREC_STRONGMEM *

 Enable/Disable simulation of Strong Memory model

 * 0 : Don't try anything special (Default.)

-* 1 : Enable some Memory Barrier when reading from memory (on some MOV opcode) to simulate Strong Memory Model while trying to limit performance impact (Default when libmonobdwgc-2.0.so is loaded)

-* 2 : Enable some Memory Barrier when reading from memory (on some MOV opcode) to simulate Strong Memory Model

+* 1 : Enable some Memory Barrier when writting to memory (on some MOV opcode) to simulate Strong Memory Model while trying to limit performance impact (Default when libmonobdwgc-2.0.so is loaded)

+* 2 : All 1. plus a memory barrier on every write to memory using MOV

+* 3 : All 2. plus Memory Barrier when reading from memory and on some SSE/SSE2 opcodes too
