[ENHANCEMENTS]
A safer solution by Dmitry Karasik for the die handler in MCE::Signal
and MCE::Core::Worker.Moved ->forchunk, ->foreach, and ->forseq sugar methods to MCE::Candy.
Stubs exist in MCE. Thus, no breakage to existing apps.Removed the link to MCE::Shared on the main page. I decided to backport
all the fixes into 1.6. The MCE::Shared link was missed and requires
the upcoming 1.7 release.
