[Zope] HELP: popen2.Popen3 on solaris 2.6 failing

[Li Dongfeng]

popen2.Popen3 caused exception in solaris 2.6.

I had a Zope product using popen2.Popen3 to open a 
long running sub-process and use select.select to
get status. Now our sun sparc machine upgraded to solaris 2.6
so I had to re-install all(I'm not root). I downloaded
  Zope-2_1_0b2-solaris-2_6-sparc.tgz
and installed it in my home directory, started using only
Z Server. All work OK but my product.

The following is a testing external method that broke the server:

from popen2 import Popen3
def test_popen3(self):
    print "Inside test_popen3"
    lp = Popen3("echo This is a test", 0, 0)
    print "After Popen3"
    return "test_select\n"

When trying the method, the server give the following error message
and restarts, the error message is at the end of the mail.

Anyone met the same kind of problem before? Using popen2.Popen3 worked
in my old solaris 2.5 installation.
