I have plans on separate out ptrace related stuff from task_struct so
that they're allocate iff they're used which will save some tens of
bytes on the task struct, so there at least is a plan to compensate
for the added cruft.

I really don't know at this point. I tried to make it share one of
the related fields but there needs to be a per-task field which is
protected by siglock and there currently isn't any, so...
