Stuff in lxss is treated "special" - files in that directory have unix numeric permissions on NTFS instead of ACL permissions. Windows doesn't know how to set those, so if win32 subsystem is updating permissions (for instance, on file save) and the linux subsystem is updating metadata (for instance, on file save), it's possible to end up in a state where neither subsystem is able to get permission to touch the file again.

For this reason, it is recommended to only edit files outside this directory from both subsystems (not to say this isn't issue-free, but it's relatively reliable.)
