| 1366 // instances of a compilation task for the same method on the | |
| 1367 // compilation queue. Consider now the case where the compilation | |
| 1368 // thread has already removed a task for that method from the queue | |
| 1369 // and is in the midst of compiling it. In this case, the | |
| 1370 // queued_for_compile bits must be set in the method (and these | |
| 1371 // will be visible to the current thread, since the bits were set | |

| 1381 // <0, 1> : in compile queue, but not yet compiled | |

| 1389 // completed, and end up introducing a "duplicate" (redundant) task. | |
