This is likely a regression. Cygwin now returns same inode number 253 
for each entry below /proc/registry node:

$ ls -1Ri /proc/registry
/proc/registry:
253 HKEY_CLASSES_ROOT
253 HKEY_CURRENT_CONFIG
253 HKEY_CURRENT_USER
253 HKEY_LOCAL_MACHINE
253 HKEY_PERFORMANCE_DATA
253 HKEY_USERS
ls: /proc/registry/HKEY_CLASSES_ROOT: not listing already-listed directory
ls: /proc/registry/HKEY_CURRENT_CONFIG: not listing already-listed directory
ls: /proc/registry/HKEY_CURRENT_USER: not listing already-listed directory
ls: /proc/registry/HKEY_LOCAL_MACHINE: not listing already-listed directory
ls: /proc/registry/HKEY_PERFORMANCE_DATA: not listing already-listed 
directory
ls: /proc/registry/HKEY_USERS: not listing already-listed directory

Last working snapshot was 2012-04-01.
