   If \a env is null, then the process is started with the same environment as
   the starting process. If \a env is non-null, then the values in the
   stringlist are interpreted as environment setttings of the form \c
   {key=value} and the process is started in these environment settings. For
   convenience, there is a small exception to this rule: under Unix, if \a env

   LD_LIBRARY_PATH, then this variable is inherited from the starting process;
   under Windows the same applies for the enverionment varialbe \c PATH.

   You can write data to standard input of the process with
   writeToStdin(), you can close standard input with closeStdin() and you can
   terminate the process tryTerminate() resp. kill().
 
   You can call this function even when there already is a running

   of the old process and deletes pending data, i.e., you loose all
   control over that process, but the process is not terminated. This applies
   also if the process could not be started. (On operating systems that have
   zombie processes, Qt will also wait() on the old process.)
