to fix this
In certain cases, a process ID may be reused between two lazy updates
of procfs's PID table. If the new associated process slot has a lower
index than the old one, this will trigger an assert in vtreefs, as the
new PID name entry is added before the old one is removed. This patch
fixes the problem by always first removing old PID name entries before
adding new ones.
