I would suggest something like:
a: b: {
    local pid = [collect "/bin/echo $$"];
    local WIP = [catenate "/tmp/ABC-" [pid]];
    mkdir [WIP]; set clearstat
    .... use of directory
    rm -rf [WIP];
}
This will get a unique name for each recipe invocation. From the rm I
assume that is what you want.
You could of course put the name gen in a function if you want.
I would leave the mkdir and rm together though just so nothin is hidden
from the future reader.
