That script has two parts: one is just an interactive algo that tells you 
what revision you should try, then you tell it what revision you really 
tried and whether it was good or bad. So it does the paperwork of keeping 
track on the current shortest path in besection. This part should work on 
any repo and any VCS system with any sort of linearity.
The other part is pcb-rnd specific - it tries to make sure you have the 
right externs at the right version and caches the compiled pcb-rnd 
executable so you don't need to recompile the same version for a different 
bisect attempt. This part won't work with anything else but pcb-rnd.
What I think we should do is this:
1. run the svn remote dump manually, to get the whole thing in a file
2. run the svnadmin import manually on this file, to see if it can import.
There are two outcomes possible:
A. it breaks; then what we have here is a "too high" version of svn rdump 
client can't properly communicate with a "too low" version of svn server. 
If we see that, we should probably ask the svn devs, or maybe report it as 
a bug - dump should be a format that works across versions, especially 
when emitted by old and imported by new.
B. it doesn't break; in that case we have a flow control problem on the 
pipe between the two processes. Maybe too much stuff is coming in from the 
net and svnadmin ic consuming it too slow and the tcp connection breaks, 
oslt. If we can prove that, we will nee to switch to svnsync.
