There is a procedure described in 'The Darkroom Cookbook' for pushing
Tri-X to 3200, while retaining shadow detail.  From memory, it involves
transferring the film to a new long tank containing a warmed hydrogen
peroxide bath for a period.  An empty spool or two at the bottom of the
long tank keeps the film suspended above the bath, in the fumes of the
hydrogen peroxide.  

I've have to admit I never tried it - although I'm planning to at some point
when I can work out the logistics.

Not correct if you're talking image quality will well processed P3200 or 
Delta. Tri-X pushed to 1600 is going to be missing major shadow detail
that 
will be in the higher-speed films which are actually right on at around 
1200 to 1600 ISO.

I disagree with unanimity.
