| Checkpoint - easy to use parent-child synchronization. |
| |
| Checkpoint is based on futexes (man futex). The library allocates a page of |
| shared memory for futexes and the id is an offset to it which gives the user |
| up to page_size/sizeof(uint32_t) checkpoint pairs. Up to INT_MAX processes |
| can sleep on single id and can be woken up by single wake. |
