I just wanted to note that the CWD is not the only thing about a filesystem that's transient -- it's contents can change over time too. This is particularly important for a long-lived process like lldb, which explicitly supports things like rebuilding an executable and then relaunching it within the same debugger session, and it also creates and deletes some files itself. So, I expect that lldb reproducers will, sooner or later, need to learn to deal with filesystems which change over time, but AFAIK the current yaml vfs thingy does not support anything like that.

Now, I am not familiar with the design principles or the implementation of the VFS classes, so I have no idea whether this speaks for or against this change, but I though it may be interesting to note that..
