It could do that but I don't think there would be any gain since it would imply
a lot of disk I/O.

A file is currently considered to be a "cygwin executable" (iscygexec is
true) if it comes from a directory mounted with a "-X" option.  In this
case spawn_guts will only prepare a UNIX-style argv and environ list for
the execed process.  Otherwise it will produce both a Windows command
and environment list and a UNIX style.
