This is not entirely correct. A *few* rigorous steps have been taken,
going back as far 1976, e.g.:
EWD 554 "A personal summary of the Gries-Owicki Theory" (March 1976)
[Published in Edsger W. Dijkstra, "Selected Writings on Computing:
A Personal Perspective", Springer-Verlag, 1982. ISBN 0 387 90652 5.]
p.s. Reading this might be a bit difficult if one has never seen
the Dijkstra/Gries "guarded command language" notation:
Edsger W. Dijkstra: "Guarded Commands, Nondeterminacy and Formal
Derivation of Programs", Comm. ACM 18(8): 453-457 (1975)
An earlier version (June 1974) is archived at:
EWD 418: "Guarded commands, non-determinacy and a calculus
for the derivation of programs".
