From: Sven Schnelle <sv...@stackframe.org>
If SIGP is set, the 'Wait for Reselection' command should jump
immediately to the address stored in the second DWORD of the
instruction. This fixes spurious hangs in the HP-UX 11.11
installer when the SIGP bit gets set by the kernel before the
'Wait for Reselection' command is executed by SCRIPTS.
