[arch-general] stability of pbzip2 ?

Hi, I'm quote fond of pbzip2's ability to multitask the compression, which comes really handy when backuping large archives of server files. But just heard from my friend: pbzip2 has stability issues, sometimes leads to corruption of archive, and hence unable to recover them. I wonder if this is true (in the sense that anyone once had a problem with pbzip2), because myself had never run into one of them. If so, it really a shame to abandon such a good tool though... -- Ian-Xue Li
