Oh, and this might explain why I'm not seeing the hang on my machine:

$ cygcheck /bin/cygpath.exe
C:/cygwin/bin/cygpath.exe
  C:/cygwin/bin\cygwin1.dll
    C:\WINNT\System32\KERNEL32.dll
      C:\WINNT\System32\NTDLL.DLL
  C:\WINNT\System32\SHELL32.DLL
    C:\WINNT\System32\GDI32.DLL
      C:\WINNT\System32\USER32.DLL
    C:\WINNT\System32\ADVAPI32.DLL
      C:\WINNT\System32\RPCRT4.DLL
    C:\WINNT\System32\SHLWAPI.DLL
    C:\WINNT\System32\COMCTL32.DLL

I'm running on Win2k, which may be significant.
