The difference between the two environments is that perl 5.14 (12.1) uses
prctl() to set the process name and perl 5.10 (SP2) doesn't. It just relies on
changing argv. The ltraces and straces I've seen bear this out.
The kernel does fill comm with the last component of the path. Perl 5.10
doesn't call prctl so it doesn't replace it. Perl 5.14 does, which is why you
see something different in /proc/pid/stat.
Passing on to perl maintainer for further discussion. In any case, it's not a
kernel issue.
