60fc29f4b5 Testrun.sh now takes the suite via the -s option. this means that you can run a single test case. 
testrun.sh now takes a "runner" via the -r option. You can pass something like "noaslr" to run all the test cases with ASLR turned off.

31795d3b7b In mpmcheck, assert that stackprobedepth words will fit into a page, so that we find out if design.mps.sp.sol.depth.constraint is ever violated. 
Format methods must have bounded stack usage for stack probing to be effective, so document this in the manual (picking the arbitrary value 64 for the bound, which should be more than enough).

3f7593f7bd Complete design.mps.thread-manager and move it from old to current. 
Better description of protection mutator context module in the "porting" chapter.
The generic thread manager mustn't assert that there is only one thread -- this would break design.mps.thread-manager.req.register.multi.

e6fb28764c Rename lockreleasempm to lockrelease. this name was changed because of a clash with a symbol in scriptworks, and that's no longer a concern. see <https://info.ravenbrook.com/project/mps/import/2001-09-27/mminfo/doc/meeting/general/1997-02-19>. if we get symbol name clashes in future, we can try the .name.single strategy, or maybe objcopy --prefix.
