+/* Helper to perform abortable blocking operations on a socket:
+ *   asocket_connect()
+ *   asocket_accept()
+ *   asocket_read()
+ *   asocket_write()
+ * These calls are similar to the regular syscalls, but can be aborted with:
+ *   asocket_abort()
+ *
+ * Calling close() on a regular POSIX socket does not abort blocked syscalls on
+ * that socket in other threads.
+ *
+ * After calling asocket_abort() the socket cannot be reused.
+ *
+ * Call asocket_destory() *after* all threads have finished with the socket to
+ * finish closing the socket and free the asocket structure.
+ *
+ * The helper is implemented by setting the socket non-blocking to initiate
+ * syscalls connect(), accept(), read(), write(), then using a blocking poll()
+ * on both the primary socket and a local pipe. This makes the poll() abortable
+ * by writing a byte to the local pipe in asocket_abort().
+ *
+ * asocket_create() sets the fd to non-blocking mode. It must not be changed to
+ * blocking mode.
+ *
+ * Using asocket will triple the number of file descriptors required per
+ * socket, due to the local pipe. It may be possible to use a global pipe per
+ * process rather than per socket, but we have not been able to come up with a
+ * race-free implementation yet.
+ *
+ * All functions except asocket_init() and asocket_destroy() are thread safe.
