Oh no!!!! Almost!

If I create a directory and then, _immediately_ after (in the same 
message tree, after 0 logical time), I send a [write ...( message to a 
[textfile] to save a file into the newly created folder, it fails 
because (I guess) the creation of the folder is "non-blocking" (so to 
say) that is it takes a small time to create it but the action is 
considered finished (and the following branch of messages is generated) 
as soon as the "command has been sent".

Any suggestions on how to check for the existence of a directory?
