Why would bash arbitrarily choose "sh.exe" as the subshell?

Hmm.

  c:\>cd cygwin\bin

  c:\cygwin\bin>ren sh.exe sh-saf.exe
  C:\cygwin\bin\sh.exe -> C:\cygwin\bin\sh-saf.exe
       1 file renamed

  c:\cygwin\bin>bash
  bash-2.05b$ (sleep 1&)	# works
  bash-2.05b$ cat /tmp/tst
  #!/bin/bash
  echo Silly
  (sleep 1 &
   (sleep 1))
  bash-2.05b$ /tmp/tst
  Silly
  bash-2.05b$ # works

If bash used /bin/sh then it would have complained when running the above.

I verified via strace that bash wasn't looking for sh.exe and settling
for bash.exe if it didn't exist, too.
