Can we assume that using the cygwin program cygstart.exe* is
also ruled out?  (*or maybe run.exe)

I don't recall that you reported the results of setting this to
a very big number as suggested by Chris Faylor.  (Please excuse
me if you did and I missed it.)  For example:

$ regtool -i set /HKLM/Software/Cygnus\
Solutions/Cygwin/heap_chunk_in_mb 2048

You might also try 3072 and 4096.  And you might want to check
that your swap file can grow big enough to handle it.
