memtime

A tool for measuring memory and time used when executing a command

memtime is a friendly tool for measuring memory usage which is fetched from a PID information of /proc/[PID]/stat by sampling. It is originally written by Johan Bengtsson in 2002.
It can be found in http://www.update.uu.se/~johanb/memtime/ or http://freecode.com/projects/memtime
But there are some limits or bugs when running in 32 bit linux platforms. Because there are overflows
   - does not allow/report more than 4GB memory usage
   - does not allow runs of longer than 21666 seconds
We have found that unsigned int is used as a counter among the programs which is a upper limit for memory and runtime measuring when run on 64 bit linux platforms. So we fix this by using long int as a counter which can allow us to measure more than 4GB memory usage and 21666 seconds.
