We don't have the primitives to go that route.
Certainly [expr rand()] is not up to that task.

I really think it's better to follow the strategy
proposed in the TIP.  The [file tempfile] command
would [open] the file itself (with the CREAT and
EXCL flags of course), then you know you won't face
any race conditions with other malicious code.
