Hi Marko, >Just wondering: What is too slow to support a shared heap? Two times slower? >Ten times?
This depends on the processor and how many locks are necessary. Using a locked instruction only if a thunk has to be evaluated, will probably increase the exection time about 30 to 50 percent on current Intel Core .. and AMD processors. On these processors a locked instructions takes at least about 20 clock cycles. On a Pentium 4 processor however this is about a 100 clock cycles.
