Fix MemoryFileSystemTest.readSymlinkLoop()

[marschall]

MemoryFileSystemTest#readSymlinkLoop() is failing

[ghost]

does this mean that sym link loop detection is no longer a feature ?

You can (in 0.6.3) create a symlink look e.g. by linking to the parent.

@OpenCAGE not sure what you mean, but you are supposed to be able to create symlinks to anything; the symlink(2) call doesn't care. It is the reading code which is in charge of loop detection if any.

[marschall]

@OpenCAGE you're right, I removed it from the feature list

[fge]

@marschall that's quite a loss :/ Is there a way to re-introduce it? I was of relying on it for some tests I need to perform for assertj's Path assertions... (see assertj/assertj#303)

[ghost]

testing for loops is easier during link creation. It might be ok by unix to create loops, but I can't see any positive use case for it.

[fge]

@OpenCAGE that's not the problem here; all Unix filesystems allow for it, if memoryfilesystem behaves differently that makes it not suitable as a Unix filesystem!

If you want to shoot yourself in the foot, you can, after all ;)
