[QBS] How to run module rules by ordered in "single-threaded" mode?

Hi all..

I in process of creating a custom module to support of an Keil C51 compiler.

Currently I have an very big problem: the C51.exe compiler is frequently
crashed when it is invoked from the Rule of module. A crash happens if
number of source files (*.c) more than one.

The interesting moment that if to run compilation manually from command
file (e.g. *.bat file) that a crash isn't present. Of course, I do it with
the same command line options which is passed to compiler from my qbs
module. I.e. command options is identically..

A main difference in that a compiler C51.exe is called by ordered in case
of the BAT file. I.e. at the same time only one copy of C51.exe process can
be active to compile of one source file. But in case of invoke from Qbs,
are launched more than one process of C51.exe at the same time
(multithreaded ??).

So seems, it is brings to crashes of the C51.exe compiler, but I am not

Thus, my question such: whether it is possible to configure the Qbs module
with some parameters to force it to work in an ordered "single-threaded"
mode? E.g. when the following Rule (operation) can't be launched, while the
previous Rule (operation) is not complete?
