B.12.9.1 Process-Level System Services

The following system services continue to be process-based: $SUSPEND, $RESUME, and $DELPRC. These services will operate on an entire process; they are not thread-based. For example, $SUSPEND issued by a thread will suspend all of the virtual processors in process, not just the calling thread. Note that on Version 7.0 you may see all but one of your kernel threads in SUSP state at certain times (such as when at a breakpoint in the debugger). This effect is a part of the debugging support and is not the result of calling $SUSPND.
