Hello,
Now that the use of task_for_pid() on intel boxes has been
tightened to use by root or processes belonging to procmod:

universal_binary/index.html#//apple_ref/doc/uid/TP40002217>
those of us relying on the helpful snippet in TN2050 have been
chopped off at the knees. Does anyone have a workaround for getting
notified when a process terminates without resorting to polling? (I
only care about processes owned by my UID.)
In addition to the kqueue suggestion (which is better for this
situation, probably), there are bootstrap namespaces.
OmniObjectMeter, for example, needs to be able to scrounge though the
target process's memory. We do this by setting up a private
bootstrap namespace and then having the target process register its
task port there-in under a well-known name.
