I have been looking at memory usage this evening and notice that we somehow have a 18mb regression between our last beta and today.  In my simple test, I load the mozilla.com start page, and look at what ps shows for RSS.  For example:


Nightly Jan 30:

USER     PID   PPID  VSIZE  RSS     WCHAN    PC         NAME

DougTs-MacBook-Pro:~ dougt$ ./builds/android-sdk-mac_86/platform-tools/adb shell ps | grep mozilla
app_52    2853  74    226100 95364 ffffffff 00000000 S org.mozilla.fennec
app_52    2899  2853  72824  19716 ffffffff 00000000 R /data/data/org.mozilla.fennec/plugin-container


Beta 3:

USER     PID   PPID  VSIZE  RSS     WCHAN    PC         NAME

DougTs-MacBook-Pro:~ dougt$ ./builds/android-sdk-mac_86/platform-tools/adb shell ps | grep mozilla
app_55    2946  74    204060 76764 ffffffff 00000000 S org.mozilla.firefox
app_55    2973  2946  70588  23284 ffffffff 00000000 S /data/data/org.mozilla.firefox/plugin-container


So, the parent process uses about 18600kb more.  Good news is that the child uses 3568kb less.
just some notes of interest.
it is bug 623999.
