ok here is a very basic setup. i hope it'll clear everything. 
the memory do NOT grow with this pipeline:

gst-launch videotestsrc ! video/x-raw-yuv,width=720,height=576,framerate=25/1 !
x264enc pass=0 ! matroskamux ! fakesink

while this pipeline the memory IS constantly grow:

gst-launch videotestsrc ! video/x-raw-yuv,width=720,height=576,framerate=25/1 !
x264enc pass=0 ! h264parse access-unit=true ! matroskamux ! fakesink

you can simple test by running both pipeline about 30 minutes. about after 5
minutes the memory usage keeps a certain level and if you watch longer in the
first case it's not increase while in the second case it's continuously
growing. 

both of the above pipeline contains only basic gstreamer's elements and both
contains matroskamux. so if matroskamux index creation taking up memory, than
why not doing the same in the first case?
