I reviewed the changes and afterwards gave HEAD ECL a test;

When doing tests with SLIME the following was caught:

lsp/trace.lsp:277:       (*step-functions* (make-hash-table :size 128 :test 'eq :lockable t)))

I also noticed in the same grep:

c/symbols_list.h:1371:{KEY_ "LOCKABLE", KEYWORD, NULL, -1, OBJNULL},
c/symbols_list2.h:1371:{KEY_ "LOCKABLE",NULL},
