-/// Raw node storage is preallocated in a contiguous memory segment,
-/// but we use an anonymous mmap so the physical memory used (RSS) will
-/// only reflect the maximum number of waiters that actually existed
-/// concurrently.  For blocked threads the max node count is limited by the
-/// number of threads, so we can conservatively estimate that this will be
-/// < 10k.  For LifoEventSem, however, we could potentially have many more.
-///
-/// On a 64-bit architecture each LifoSemRawNode takes 16 bytes.  We make
-/// the pool 1 million entries.
