NetBSD considers the thread to be part of the context, and calling swapcontext() with a context obtained from another thread will preempt the other thread in order to execute synctask_wrap(). And here we break because synctask_get() will not retreive the approriate task, as it was set in thread specific storage of another thread. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz address@hidden
