Feature #4689:  /proc/$PID/environ in Linux
http://redmine.ruby-lang.org/issues/4689

Author: Eric Wong
Status: Assigned
Priority: Low

Category: core
Target version: 1.9.x


 I wanted to inspect the environment of a long-running process[1] and I
 noticed Ruby 1.9.2 moves environ for argv storage when modifying $0.
 
 Can we do this lazily and only as a last resort when argv doesn't have
 space?  I can look into supplying patches this weekend, at least for
 the Linux use case.
 
 I remember this worked fine in 1.9.1 even with minor $0 modifications
 in my code.
 
 
 [1] I use this command: tr '\0' '\n' < /proc/$PID/environ
