Collections-ul.586 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.212
Symbol table changes: - ensure that enumerations stay consistent - avoid read-write and write-write race conditions - added a safe #condenseNewSymbols method, which is a replacement for former unsafe methods (#shutDown: and #compactSymbolTable). It's also automatically triggered whenever there are more than 1000 NewSymbols. - deprecated #compactSymbolTable - updated some comments
Note that interning many symbols is a bit slower, but thread safety is more important.

System-ul.688 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.212
Replaced ExternalSemaphoreTable with ExternalObjectTable to provide faster registration, and give better support to the current users of external objects. Notable changes:
- the table is a separate object instead of a few class side methods - the whole API can be found in SmalltalkImage in the external objects category - #newExternalSemaphore, #newExternalSemaphoreDo: and #newExternalSemaphores: provide fast and easy creation and registration of Semaphores - #unregisterExternalObjects: can unregister multiple objects faster - #externalObjects will return a copy of the externalObjectsArray - better scalability - the maxExternalSemaphores VM parameter will be incremented as the externalObjectsArray grows
