The problem seems to be that a partition is found before the disk
appears. More specifically, the partition needs to be before *any*
disk. (A different but related bug is that the library assumes
all partitions appear immediately after the disk line).
So: sda, sda1, sda2 = ok
sda1,sda2,sda = crash
sr0, sda1, sda2 = ok, but sda1 is "linked" to sr0
The problem now is, under what conditions do these odd
/proc/diskstats occur and what interpretation should
vmstat make of the situation? Ignore the partitions?
Raise an error? re-map the disk->partition links
after reading the file?
