[collectd] memory leak in 5.4.1 (possible plugin rrdtool)

[Sergey]

Hello.

Version 5.4.1 have a memory leak. I found http://collectd.org/bugs/661
but it is about rrdcached. I use rrdtool some last days (see my subject
about "rrdc_update ... failed with status -1").

Collectd consumes a lot of memory after a day of works since this moment:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
 6859 root      20   0 3756144 1.058g   3068 S 7.979 54.95 225:28.54 collectd
