Yes, absolutely, although I'm sorry it has taken so long. Between
thanksgiving and the impending end of the semester things have been a
bit hectic. Nevertheless, I just finished putting together a script to
record some metics from /proc/vmstat and /proc/[pid]/statm, so at this
point I'm ready to finally take some data. Any suggestions for
particular patterns to look for in the numbers or other metrics to
record are welcome. Cheers,

- Ben
