Note that this is possible with recent versions of GNU Parted, because
it uses the BLKPG ioctls instead of BLKRRPART.

Sure.
If so, could the error message
include this info, so users know they need to reboot.
There is:
printf(_("\nWARNING: Re-reading the partition table failed with error %d: %s.\n"
"The kernel still uses the old table. The new table will be used at\n"
"the next reboot or after you run partprobe(8) or kpartx(8)\n"),
errno, strerror(errno));
Example old output:
[...]
The new table will be used at the next reboot.
I think it's pretty obvious that you need to reboot.
