Well, that example is not particularly useful, right?  It merely shows 
that a sub-shell process ran and exited, all without changing the 
current directory.  The original shell process, of course, maintained 
its current directory as it would with the execution of any 
subprocess.  It would really suck if the root user's current directory 
kept changing while he ran a script in the background :-) 

khermans@hermbuntu-desktop:/tmp$ cat foo.pl 
#!/usr/bin/perl 
print "Current dir is..." . `pwd`; 
print "Changing dirs...\n"; 
print "New dir is..." . `cd /etc/; pwd`; 
khermans@hermbuntu-desktop:/tmp$ perl foo.pl 
Current dir is.../tmp 
Changing dirs... 
New dir is.../etc 
khermans@hermbuntu-desktop:/tmp$ pwd 
/tmp
