This section describes the garbage collector (GC) in 32-bit LispWorks 6.1.
In LispWorks for UNIX and LispWorks for Macintosh, the implementation is not significantly different to that in LispWorks 4.x or LispWorks 5.x.
In LispWorks for Windows and LispWorks for Linux, the implementation has changed since LispWorks 4.x and you may notice performance improvements relative to those versions.
