[cgiapp] Intermittent problem with sessions when redirecting

[Lyle]

Hi All,
  I just wasted the last 2 hours going round in circles trying to figure 
out what is going wrong. Everything works find if I return the normal 
text/html header. But as soon as I use a redirect instead, the session 
is sometimes lost.

  I added logging to try and figure out what's happening. At the bottom 
of this email are 3 examples, 2 of which fail, one gets through. No code 
changes were made during the tests. You can see from the 2 that fail, 1 
doesn't even make it to teardown, the other starts teardown but doesn't 
finish. The one that passes completes teardown.

  From this I take it that something is going wrong and causing the 
process to die prematurely. This is losing the session file, even though 
the code to create the session has already ran and completed. Nothing is 
showing up in the error logs.

Any advice very much appreciated, I'm banging my head against a wall here :(

P.S. Just noticed I'm not the only one experiencing this
