+// The queue is also wait-free in the common path (except if more memory
+// needs to be allocated, in which case malloc is called).
+// Allocates memory sparingly, and only once if the original maximum size
+// estimate is never exceeded.
+// Tested on x86/x64 processors, but semantics should be correct for all
+// architectures (given the right implementations in atomicops.h), provided
+// that aligned integer and pointer accesses are naturally atomic.
+// Note that there should only be one consumer thread and producer thread;
+// Switching roles of the threads, or using multiple consecutive threads for
+// one role, is not safe unless properly synchronized.
+// Using the queue exclusively from one thread is fine, though a bit silly.

+    // The high-level queue is a circular linked list of blocks; again there

+    // enqueued, provided the block is not full.
+    // The producer thread owns all the tail indices/pointers. The consumer
+    // thread owns all the front indices/pointers. Both threads read each
+    // other's variables, but only the owning thread updates them. E.g. After
