-Vit-
a major problem with HD is that we cannot run enough threads to use up the CPU before running out of memory

It was the first real problem we faced with SVP

The current solution (modified Avisynth version) is good for SVP, may be it can be good for you too.
There're two mods in it:
1. distributor code is sometimes more effective (= needs less threads for the same processing speed for FRC)
2. sizes of internal caches between filters are limited by exact number of frames, not by global SetMemoryMax value and it's working great with linear video processing. For example one can use pel=4 with 1080p clip in MVTools with this mod.
So the total memory consumed depends on <number of filters>*<size of each cache>.

In case you're interested:
- global script value "svp_scheduler=true" turns on both mods, cache size is something like <num of threads>*2
- "svp_cache_fwd=<num_of_frames>" - set the exact cache size

And don't forget about "4gb patch"
