// The GParted authors have found a bug in libparted that causes it to intermittently
// not commit changes to the Linux kernel, probably a race. Until this is fixed in
// libparted, the following patch should help alleviate the consequences by just re-trying
// committing to the OS if it fails the first time after a short pause.
