Altough I should know (I am one of the maintainers), honestly I don't. The issue is notoriously hard to get at (especially on windows). The issue is however actively discussed by the C++ standards group. The main questions are about proper interaction with exceptions. If you carefully rethink the need for cancellation you most likely will find that you really will need cancellation rarely. You almost always can use some other interthread communication mechanisms. You also might take a look on my thread alerter which I have posted to the vault quite some time ago. This is written on top of Boost.Thread but does not implement cancellation. However you will be able to "wake up" a thread that is in some form of "waiting". Often this is what you really need. Full blown cancellation often is a too coarse grained tool anyways. Roland
