Uhm, I didn't read your implementation, but the proper thing to do for a VM which doesn't care about the external objects table (splObjs at: 39) growing, is returning nil from maxExternalSemaphores, like it will for pre-Cog VM's.
Otherwise, you'll get a domain error when you eventually (yes,yes, it'll take awhile) run out, and maxExternalSemaphoresSilently: tries to set the new max to a value that won't fit in the 16bit header field where it expects to put it…
