Eric van Gyzen 427f12f150 libprocstat kstack: fix race with thread creation
When collecting kernel stacks for a target process, if the process
adds a thread between the two calls to sysctl, ignore the additional
threads.  Previously, procstat would print only a useless error
message.  Now, it prints a consistent snapshot of the stacks.
We know that snapshot is already stale, but it could still be stale
even with a more complex fix to reallocate and retry, so such a fix
is hardly worth the effort.
