The stack repair option resets the stack to a known state, de-commits unneeded memory and restores the guard page. Back to top Version 3.0 Smalltalk MT 3.0 comes with a vastly improved memory management system and industrial strength build tools. Highlights of the new version New memory management system with a growable, private heap. Components such as ActiveX can dramatically reduce their reserved memory range at startup yet allocate as much memory as needed at runtime. On-demand garbage collection .
Garbage collection runs in separate threads and can be paused or completely stopped and restarted.
This results in better runtime performance and facilitates real-time applications. Free-threaded support in the base image. Inlined structure accessors . Fields in structures and nested structures can be accessed inline, so that reading or writing to a field can be accomplished in a single CPU cycle. Structure optimizations are integrated with the native floating point implementation.
