OK, that makes sense. In a lot of simple cases you can get by without regaining the same pid; there's an implementation of checkpointing in GDB that works by injecting fork calls into the child, and it is useful for a reasonable selection of single-threaded programs. -- Daniel Jacobowitz CodeSourcery _______________________________________________ Containers mailing list [EMAIL PROTECTED] https://lists.linux-foundation.org/mailman/listinfo/containers _______________________________________________ Devel mailing list Devel@openvz.org https://openvz.org/mailman/listinfo/devel
