Why not just use postfile? Stata will then automatically put whatever you specify into a new Stata dataset, which can readily be analyzed, combined with your original data, whatever you want.

So I want to run 10,000 iterations of a process, but I'm not using Stata
SE, so I can't put more than 800 iterations in a given column of a matrix.

The problem is that if I want to do summary statistics, on the different
estimates, I would normally just use svmat to turn the matrix into a
variable and then 'summarize' that.

Is there any way to take two variables, say X and Y, and put them end to
end (ultimately creating a dataset that has 10,000 observations, where
each observation is an outcome).

I'm not quite sure that I follow you, but you can use a -tempfile- to save
the first batch, create the second batch, and use -append- to put them
together end-to-end, -save , replace- back to the temporary file, and
continue until your iterations are done. (Illustrated below.)
