+ * As of July 2007, all known versions of the Linux kernel will sometimes

+ * when the low-order 15 bits of the supplied shm ID match the slot number
+ * assigned to a newer shmem segment).  We deal with this by assuming that
+ * EIDRM means EINVAL in PGSharedMemoryIsInUse().  This is reasonably safe
+ * since in fact Linux has no excuse for ever returning EIDRM; it doesn't
+ * track removed segments in a way that would allow distinguishing them from
+ * private ones.  But someday that code might get upgraded, and we'd have
