synthetic IO workload - open with/without create flag
Currently, when an
open f; call is made in the synthetic IO language, the workload generator assumes that the open corresponds to a create. Of course, we'd like a distinction between the two. Looks like we'd have to descend into the IO language flex/bison files shudder.
We could either add a new call in the language,
create, for this purpose, and propagate the change throughout the parser and workload interface, or add an optional argument to open that indicates the flag.
