Uninstalled distribution package for plan9 and got .tgz at:

   http://swtch.com/plan9port/plan9port.tgz

MD5 checksum matched. Unpacked to /usr/local, executed ./INSTALL and
added recommended variables to the system profile.

   $ echo $PATH ----- $PLAN9 | tr ': ' '\n\n'
   /usr/local/bin
   /usr/bin
   /bin
   /usr/local/sbin
   /usr/sbin
   /sbin
   /usr/bin/core_perl
   /usr/local/plan9/bin
   -----
   /usr/local/plan9

Changed the test script, now named test.rc, to:

   #!/usr/local/plan9/bin/9 rc
   echo first at path: $path(1)
   for (i in `{seq 1 5}){
       if (test $i -eq 3) {
           echo $i equals 3
       }
       if not echo $i is different from 3
   }

Running /home/mauricio/test.rc:

   first at path: /usr/local/plan9/bin
   1 is different from 3
   2 is different from 3
   3 equals 3
   4 is different from 3
   5 is different from 3

Now with listen1 and dial:

   $ /usr/local/plan9/bin/9 listen1 'tcp!localhost!8080' /home/mauricio/test.rc &
   $ /usr/local/plan9/bin/9 dial 'tcp!localhost!8080'
   first at path: /usr/local/plan9/bin
   1 equals 3
   2 equals 3
   3 equals 3
   4 equals 3
   5 equals 3

My platform:

   $ uname -a | fmt
   Linux dumbo 2.6.38-ARCH #1 SMP PREEMPT Sun Apr 17 15:18:58 CEST 2011
   x86_64 Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz GenuineIntel GNU/Linux

This is really weird. I don't even know what could I check. 'listen1'
source code is pretty clean, and it calls command and args with a simple
'exec' call. The only thing that was also unusual is that the 'net'
variable, which is supposed to be set to a directory, is always blank,
but the line with 'putenv' and 'net' in 'listen1.c' is commented out,
so this is to be expected.

Thanks,

Maurício
