They continue to run. If you do step in the current thread and the
thread is
suspended as a result, the other threads run until the current
thread regains
control.

Do you mean you want debugger commands that suspend or activate
threads
independently of debuggee logic? If you do and that's possible, we
should
provide the commands.
Yep.
My experience is that it can sometimes be difficult to debug a thread when
the other threads continue to run. For example, I may have one thread
generating data and writing to a queue and I have another thread reading
from that queue. If I try and debug the reading thread, the writing thread
continues to put stuff in the queue. The queue then gets full and starts to
cause other side effects.
I would therefore like to be able to temporarily suspend the writing thread.
I can, of course, work around this by temporarily changing my code or
setting additional breakpoints. However being able to do it directly with a
debug command is going to be easier, especially when the number of threads
starts to multiply or the thread is in a third party package.
