+/* Maximum number of bytes to read or write in a single system call.
+   This can be useful for system calls like sendfile on GNU/Linux,
+   which do not handle more than MAX_RW_COUNT bytes correctly.
+   The Linux kernel MAX_RW_COUNT is at least INT_MAX >> 20 << 20,
+   where the 20 comes from the Hexagon port with 1 MiB pages; use that
+   as an approximation, as the exact value may not be available to us.
+
+   Using this also works around a serious Linux bug before 2.6.16; see
+   <https://bugzilla.redhat.com/show_bug.cgi?id=612839>.
+
+   Using this also works around a Tru64 5.1 bug, where attempting
+   to read INT_MAX bytes fails with errno == EINVAL.  See
+   <https://lists.gnu.org/r/bug-gnu-utils/2002-04/msg00010.html>.
+
+   Using this is likely to work around similar bugs in other operating
+   systems.  */
