The exec function from the dos unit always waits till the started application closes.
If you don't want to wait, use the linux unit:

 if Pid=0 then
   execl ('/usr/bin/gnome-help-browser man:manual_page');
   waitpid(PID,WAIT_NOWAIT) // NOWAIT means reaturn at once.

For the exact syntax of execl,waitpid, see the documentation and examples
of the linux unit.
