12:57 AM Ruby Revision 2b22593a (git): Simplify subclasses list, remove from Box

Currently we maintain the subclasses list for two separate purposes (we essentially have to different relationships we're putting into the same list):
1. On a T_MODULE, we track the T_ICLASSes created to include it into
other classes... jhawthorn (John Hawthorn)

12:12 AM Ruby Bug #21856 (Closed): Massive performance degradation of `rb_obj_free` for `T_CLASS` since Ruby 4.0

I merged my proposed design, which should restore Ruby 3.4's performance https://github.com/ruby/ruby/pull/16363 (forgot to tag this issue in the commit message, sorry)
I'm going to look into backporting this to Ruby 4.0. We usually d... jhawthorn (John Hawthorn)

10:56 PM Ruby Revision 6721ec26 (git): Include free_immediately: false in heap dumps

This adds "free_immediately: false" to the heap dump for any T_DATA
which doesn't specify RUBY_TYPED_FREE_IMMEDIATELY. These are the objects
which end up as T_ZOMBIE and will have their dfree callback deferred to
later when the program i... jhawthorn (John Hawthorn)

03:56 AM Ruby Revision 5c81ba21 (git): [ruby/rubygems] Make SafeYAML.load an alias of safe_load

Using Psych, load was actually more restrictive than safe_load. Using
Gem::YAMLSerializer they were identical. We might as well use the same
path for both methods.

03:56 AM Ruby Revision 77507870 (git): [ruby/rubygems] Use safe_load from owner_command

This had been the only user of Gem::SafeYAML.load for a long time. We
might as well be consistent with all other uses and use safe_load.

03:56 AM Ruby Revision 0c6972b9 (git): [ruby/rubygems] Restore original SafeYAML.load under Psych

This was changed to unsafe_load with the swap to YAMLSerializer. But
this method did not previously do an unsafe load and we shouldn't
provide that.

12:41 AM Ruby Revision 764a245e (git): Fix M:N threads under OpenBSD

OpenBSD requires MAP_STACK for memory regions used as thread stacks.
However it seems to error with "Invalid argument" unless the permissions
include both PROT_READ | PROT_WRITE.
We should be able to satisft this by re-mmapping over our... jhawthorn (John Hawthorn)
