* which starts the 32-bit process via an undocumented command-line
* switch '/z', which syntax is:
* COMMAND.COM /z\bAPPNAME.EXE
* notice the '\b' character inserted in-between. Then COMMAND.COM
* issues a BOP_CMD 08h with AH=00h to start the process).
*
* Instead, we do the reverse, i.e. we start the 32-bit process,
* and *only* if needed, i.e. if this process wants to start a
* new 16-bit process, we start our COMMAND.COM.
*
* The problem we then face is that our COMMAND.COM will possibly
* want to start a new COMSPEC, however we do not want this.
* The chosen solution is to flag this case -- done with the 'Reentry'
* boolean -- so that COMMAND.COM will not attempt to start COMSPEC
* but instead will directly try to start the 16-bit process.
