When designing this, if you would, give some though about different
models for allowing a build to be stopped before completion. This
includes the case where there is only one thread executing the build
as well as the multi-thread case. Given the deadlock dangers of
Thread.stop(), Thread.suspend(), etc. it seems to me that we need some
sort of consistent approach accross tasks to be able to tell them to
stop what they are doing, particularly in the case where they have
forked a process that may take some time to complete. Perhapse an
approach can be developed whereby the current tasks would by default
be considered "halt unfriendly" until someone gets around to
implementing whatever required method provides the mid-build halting

Obviously my current  motive is the GUI, where the user will want to
halt a build after it has started (currently accomplished with a nice
Ctrl-C). But there are other cases where this will be needed,
including remote monitoring of builds, etc.
