[svn-r12760] Description:
Speculatively attempt to read in the entire first chunk in object header
with the object header prefix. If successful (which it is most of the time),
this reduces by 1 the # of I/Os required to read in the object header. Since
the object header typically was taking 2 I/Os, this should cut the number of
I/O operations when opening an object's header in half.
Tested on:
FreeBSD/32 4.11 (sleipnir) w/threadsafe
Linux/32 2.4 (heping) w/C++ & FORTRAN
