[jsc-dev] Signal handler API

[Keith Miller]

Hi all, 

We have been using signals for more and more features inside JSC. At this point, the gains we could get from using signals everywhere are probably worth the potential downsides. The main potential issue is breaking compatibility with API users. This isn’t likely to be a major issue, however, and we can initialize our handlers lazily, which should prevent most backwards compatibility breakages.

I opened a bug on this: https://bugs.webkit.org/show_bug.cgi?id=170976. The bug has a proposed bare-bones API for commentary.
