forks

Changes for version 0.27

Bug fixes *****
forks::shared now supports perl 5.9.0 and later (with a source filter). The requirement for a source filter is hopefully just a temporary solution until Attribute::Handlers can access the 'shared' attribute again (which perl 5.9 and later currently prevent, perhaps because they consider it a reserved word).
Corrected perl 5.6 support, regarding incompatible XS function Perl prototypes (broken since 0.16).
All internal %INC manipulation is now done at compilation (require) time. This corrects cases where modules that 'use threads::shared' before forks::shared has been loaded actually load ithreads-native threads::shared.
Corrected bug regarding handling forks-server operation deferred signals (which was preventing them from being executed when they should be executed).
Miscellaneous changes *****
Forks now uses Perl core module Attribute::Handlers for 'shared' variable attribute handling. This also insures compatibility with any other modules that may use Attribute::Handlers.
Removed BUS, FPE, ILL, SEGV, and SYS from list of "forks-aware" signal handlers for better cross-platform portability.
Added POD strongly encouraging use of forks and forks::shared as FIRST modules.
Now tracking last known CORE::GLOBAL::exit at require time, and resetting at END. This should insure that cases where forks wasn't first module to be loaded allows for other modules to still use their own custom exit methods.
Moved 5.6.x source filter from forks.pm to forks::shared.pm, where it belongs.
Added appropriate disabled functions (without prototypes) for perl 5.6.x when forks::shared is disabled if was loaded without loading forks first).
