| 4349 // An Event wraps a win32 "CreateEvent" kernel handle. | |
| 4350 // | |
| 4351 // We have a number of choices regarding "CreateEvent" win32 handle leakage: | |
| 4352 // | |
| 4353 // 1: When a thread dies return the Event to the EventFreeList, clear the ParkHandle | |
| 4354 // field, and call CloseHandle() on the win32 event handle. Unpark() would | |
| 4355 // need to be modified to tolerate finding a NULL (invalid) win32 event handle. | |
| 4356 // In addition, an unpark() operation might fetch the handle field, but the | |
| 4357 // event could recycle between the fetch and the SetEvent() operation. | |
| 4358 // SetEvent() would either fail because the handle was invalid, or inadvertently work, | |
| 4359 // as the win32 handle value had been recycled. In an ideal world calling SetEvent() | |
| 4360 // on an stale but recycled handle would be harmless, but in practice this might | |
| 4361 // confuse other non-Sun code, so it's not a viable approach. | |
| 4362 // | |
| 4363 // 2: Once a win32 event handle is associated with an Event, it remains associated | |
| 4364 // with the Event. The event handle is never closed. This could be construed | |
| 4365 // as handle leakage, but only up to the maximum # of threads that have been extant | |
| 4366 // at any one time. This shouldn't be an issue, as windows platforms typically | |
| 4367 // permit a process to have hundreds of thousands of open handles. | |
| 4368 // | |
| 4369 // 3: Same as (1), but periodically, at stop-the-world time, rundown the EventFreeList | |
| 4370 // and release unused handles. | |
| 4371 // | |
| 4372 // 4: Add a CRITICAL_SECTION to the Event to protect LD+SetEvent from LD;ST(null);CloseHandle. | |
| 4373 // It's not clear, however, that we wouldn't be trading one type of leak for another. | |
| 4374 // | |
| 4375 // 5. Use an RCU-like mechanism (Read-Copy Update). | |
| 4376 // Or perhaps something similar to Maged Michael's "Hazard pointers". | |
