| .SH ARGUMENTS |
| threaded - true if list should be thread-safe. |
| .br |
| root - performance parameter (see above). |
| .br |
| maxLevel - performance parameter (see above). |
| .br |
| flushLimit - max deleted items to keep cached before |
| .br |
| forcing a flush. |
| .br |
| freeValue - callback made whenever a value is flushed. |
| .br |
| ctx - context to pass to <freeValue>. |
| |
| .SH DESCRIPTION |
| Returns a new skip list. If <threaded> is true, list is |
| multi-thread safe. <root> and <maxLevel> determine |
| performance and expected size (see discussion above). |
| <flushLimit> is for threaded lists and determines the |
| maximum number of deleted items to keep cached during |
| concurrent searches. Once the limit is reached, new |
| concurrent reads are blocked until all deleted items are |
| flushed. |
| |
| MT-Level: Safe. |
| |
| .SH "RETURN VALUE" |
