how does one set a breakpoint in a process started with proccreate? say i h=
ave:

someproc()
{
    recv(chan, x);
    somefunc(x);
}

threadmain()
{
    proccreate(someproc,...);
    do_something();
    send(chan, somex);
    ....
}

i want to break just before the call to 'somefunc()' in the process
executing someproc()

i'm trying with:

acid: bpset(do_something)
acid: cont()
/* bp reached */
acid: threads()
/* see pid of someproc */
acid: setproc(pid)
acid: bpset(somefunc)

and here i get 'waiting...' but i can't go back to the main thread and
do a cont(), so the send() never happens...

please unleash your knowledge upon me.

thanks.
