Abstract
Mutual exclusion is typically employed for multiprocess
synchronization. However, Massalin and Pu [MP91], and
Greenwald and Cheriton [GC96] have implemented com­
plete operating systems using non­blocking synchronization
instead of mutual exclusion. Although most operating sys­
tems are implemented using procedural languages, both of
these systems have significant object­oriented characteris­
tics. We show the interaction of non­blocking synchroniza­
tion and object­oriented language design for operating sys­
tems, and present a proposal for an implementation of the
Java programming language with non­blocking synchroniza­
tion based on functional arrays. We present an experimental
plan to run portions of a Java operating system under our
