On return, the parameter "its" contains either the iteration
number at which convergence was successfully reached, or the
negative of the iteration at which divergence or breakdown was detected.
<P>
Currently only supported by <A HREF="../KSP/KSPType.html#KSPType">KSPType</A> of KSPPREONLY. This routine is usally
only used internally by the BiCG solver on the subblocks in BJacobi and ASM.
