Dave Lewis uploaded a new version of VMConstruction-Plugins-OSProcessPlugin to project OSProcessPlugin: http://www.squeaksource.com/OSProcessPlugin/VMConstruction-Plugins-OSProces… ==================== Summary ==================== Name: VMConstruction-Plugins-OSProcessPlugin-dtl.37 Author: dtl Time: 22 December 2012, 3:08:51 am UUID: e3c06c1b-76d8-4025-9d13-5fe582618c62 Ancestors: VMConstruction-Plugins-OSProcessPlugin-dtl.36 OSProcessPlugin 4.5.1 Use an alternate signal stack to avoid consuming native stack space. This prevents stack usage problems when running on Cog (stack depth exceeded when a signal is being handled). Adapted from VMConstruction-Plugins-OSProcessPlugin.oscog-eem.38 with the following changes: - Always use sigaltstack if the platform supports it (i.e. do not test for Cog). - If SQ_ONSTACK is not defined, then assume the platform cannot support signalstack and use the default stack. Use macros to define away unsupportable code. - Fix some type declarations to address int/pointer comparison - Use #isDefined:inSmalltalk:comment:ifTrue:ifFalse:

Correct some of the signal numbers. Depends on VMMaker.oscog-eem.233 as it no longer uses asSymbol.
