I am using AIX 4.3.1 and 4.3.2 on two different machines (one is
64 bit, another is 32 bit) - I always get 0 block reads and writes
from getrusage(), regardless of how much data I read or write. This
despite the fact that the major and minor page faults show up as
fairly high numbers (a few thousands).
Can anyone confirm if this is a known limitation of AIX? Is there
any other system call I can use to get the right block reads/writes?
