The code I provided does just that -- allows you to run a program without
waiting on a return value.  No GUI is needed, but it does use the Windows API and
Bernie's windows engine.  To run something several times without any interaction,
just do:

handle = child_process("program.exe")
child_close(handle)
handle = child_process("program.exe")
child_close(handle)
handle = child_process("program.exe")
child_close(handle)
handle = child_process("program.exe")
child_close(handle)

All 4 instances will start up nearly simulataneously, and the calling program
can go ahead and exit if desired...
