David,

two more questions please.

1.) What happens if I send multiple SIGSTOPs or SIGCONTs to the
thread? Does she handle (i.e. ignore) that properly?

2.) What happnens when I send a SIGSTOP in the middle of a running GC?
Will it stop immediately? Or will it take a while?
I suppose that a few more sectors will be examened and written...
(10ms, 100ms, 1000ms ...???)
Will it then just continue after a SIGCONT? Or will start all over again?

Thanks!

Steven
