I didn't realize that LVM could handle this scenario. Thanks for pointing that out.
To be honest, I never like to make changes to the partition table of a disk without rebooting or hotplugging the disk. The kernel sometimes doesn't refresh its view of the partition table (or has this been fixed in newer kernels?). So while online resize of physical (windows) partitions without rebooting may be possible in theory, I'm not sure if I would choose that route for an internal disk.

I believe you can have the partition table reread while one or more of the partitions have mounted filesystems on them in the 3.6 kernel now.
That may be a reason for the attempted change in f18. The ability to extend a partition online without needing lvm.

Posted this further above, but this has become a rather lengthy comment thread.. just run partprobe. I've used this with mounted in-use FSs many times without any problems.
Disclaimer: I have no idea if doing this is dangerous, but it has never bitten me.
