10:48 PM Ruby Feature #21700: `IO::Buffer.map`: offset argument is "broken" and needs to be made more useful

This makes sense to me. However it might mean we need to return a slice (which IMHO is probably okay). The alternative is to expose the internal implementation and force the user to deal with all that shit. We should also document clearl... ioquatix (Samuel Williams)

07:40 AM Ruby Bug #21672: `IO::Buffer.new` does not check that flags are valid

Thanks, I'll review. IIRC, the flags provided can be advisory, e.g. a small buffer but use mapped memory. ioquatix (Samuel Williams)

03:50 AM Ruby Feature #21642: Introduce `IO::ConnectionResetError` and `IO::BrokenPipeError` as standardized IO-level exceptions.

Thanks for your feedback. I understand your point and I think it makes sense.
"Connection Reset" and "Broken Pipe" have well defined meanings. On the face of it, I don't know what "CloseUnrecoverable" means. Is there a concept like this... ioquatix (Samuel Williams)

10:55 PM Ruby Feature #21642 (Open): Introduce `IO::ConnectionResetError` and `IO::BrokenPipeError` as standardized IO-level exceptions.

Currently, different IO implementations in Ruby raise inconsistent exception types when a connection is reset or broken.
For example:
```ruby
# Plain TCP socket:
socket.read_nonblock(1024)
# => Errno::ECONNRESET
# SSL socket:... ioquatix (Samuel Williams)

04:42 AM Ruby Bug #21633 (Open): A `rb_thread_call_without_gvl` loop can cause the fiber scheduler to ignore signals.

The gRPC gem calls `rb_thread_call_without_gvl` in a loop, and doesn't exit when interrupts are delivered if `Thread.handle_interrupt(::SignalException => :never)` is used by the scheduler to create a safe point for asynchronous signal h... ioquatix (Samuel Williams)

10:17 PM Ruby Bug #19461: Time.local performance tanks in forked process (on macOS only?)

Just for reference, on the lastest macOS, the issue still appears:
```
% clang localtime_test.c
% ./a.out

In parent
monotonic = 0.002930000
cputime = 0.002454000
In child

A slightly different change may be required for 3.3 and 3.2 backports: https://github.com/ruby/ruby/commit/e900e9fc9ace5e36de5170c83df0f56167e4c8a9 ioquatix (Samuel Williams)
