This is a process that was published in Rangefinder magazine many years 
ago. I believe it's an old Agfa method.
Apparently Tri-X can be pushed to ISO 12000-25000. I have the article 
somewhere in my darkroom. If I find it, I'll send a pdf to anyone who 
might see some use for it.
But I'm sure an email to Rangefinder could elicit the formula from them.
I'm just going from memory on this, so there might be some inaccuracy, 
but overall, and with testing it's sound.

The hydrogen peroxide has to be heated to 100 degrees. A lab hot plate 
is best, where the whole surface can held to within a 1/4 of degree of 
the set temperature. Place a 120 reel in a SS tank and then pour the 
heated solution to just below the top of the reel. You can't have the 
film touch the solution.
After processing the film half way in the developer, suspend it over 
the HP vapors for a predetermined amount of time. It can take several 
minutes. Then return to the developer for the remaining amount of 
processing time. The rest is cookbook.
I've seen images made with this method. the images looked virtually 
grainless with a surreal quality, as though somebody slightly lifted 
the curtain of night to let a bit a sunlight in.
