Oh - under "normal" conditions, backticks and pwd work just fine - 
main::(-e:1):   exit 0
  DB<1> x qx |pwd|
0  '/home/admin
'
  DB<2> x $?,$!
0  0
1  ''
  DB<3> q

But, in my program, I set a breakpoint to stop when cwd() returns undef. After that point, which is several hundred data files into the execution of the program, the weird behaviour is observed.

So - I'm not sure I understand all the responses here, not being much of a linux OS and forking geek. Is there a reason the believe that backticks cause memory leaks ? Is there an alternative way for Cwd::cwd to return the current path without 'pwd' ? How can I persuade it to do so, when it is used as a sub-module inside Archive::Extract which I am calling ?
