Name of thin process

Is possible call the thin process "thin" and not "ruby" ? So I can manage my process in a better way.

There is an example of top in my prod evn:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

4991 root 20 0 82884 59m 3416 S 0 6.2 1:56.17 mongrel_rails

5006 root 20 0 72796 53m 2368 S 0 5.7 0:57.04 mongrel_rails

28234 root 20 0 54032 42m 5252 S 0 4.4 0:16.26 ruby (is thin)

5031 root 20 0 65372 42m 3380 S 0 4.4 0:38.45 mongrel_rails

28232 root 20 0 52248 39m 4156 S 0 4.2 0:14.90 ruby (is thin)

5130 root 20 0 61232 37m 3224 S 0 4.0 0:13.69 mongrel_rails

5037 root 20 0 59736 36m 3868 S 0 3.9 0:44.42 mongrel_rails

So I can make difference from thin a ruby process

Thanks!
