I didn't mean to discuss for which filesystems on HP-UX which optimization
may be worthwhile. (Probably it's reasonable to treat NFS on HP-UX like
NFS on other platforms.)
Rather I meant to say that in order to get 'struct statfs' defined, a
simple "#include <sys/statfs.h>" is not enough, and this would be better:
