I know this is not going to be a popular opinion with you, but sometimes opening a file
is just too expensive. 1 RPC roudntrip to open a file and then another one to close it.
Also some files could not be opened (fs corruption).
Anyway, I got your point and there will be a solution. I was just hoping there was a way
to do it because what if e.g. I need to create something new, not do something with already
existing stuff, certainly there's no way to get an fd from a not yet existing fs object.
Bye,
Oleg
