Changes and Bugs Fixed

The following are changes between v3.2.8.1 and v3.2.9:

AlmostOutOfMemory during recursion to Smalltalk

If an AlmostOutOfMemory was signalled while the process had recursed from C back into Smalltalk, it was not correctly deferred or handled. This resulted in an error that prevented commit, with an uninformative message "ErrorC during index Recursion to Smalltalk". (#45633)

Large code load did not use memory efficiently

When loading a large number of classes, the handling of these classes within the memory spaces of temporary object space was not optimal, and could result in poor performance. (#45640)

A new cache statistics has been added to assist in diagnosing problems of this kind:

ClassesCreated (Gem)
Number of Classes created in VM Memory since start of session.

Cache Statistic PercentCpuIdle may have invalid value on AIX

AIX only

The calculation for the cache statistics PercentCpuIdle was subject to a rounding error, which resulted in values of -1 recorded in statmonitor data. VSD displayed this as an unsigned int, 4294967295. (#45654)

Extent growth during multithreaded scan can cause SEGV

In versions 3.2 and later, if the extents grow (e.g., they are not pregrown and the repository runs out of space) during a multithreaded scan operation, there is a risk of SEGV. (#45622)
