  /* 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 is likely to work around similar bugs in other operating
     systems.  */
