Hang on, I have a workaround for that problem.  It works fine when
using the long path prefix \\?\ in the call to CreateProcessW.
Unfortunately I had to add code to remove the \\?\ prefix for paths
which fit into 260 chars to avoid problems with native Win32 apps so
that's kind of a chicken-egg.  Hmm, tricky.
