In this test, jemalloc and tcmalloc are both more hesitant to
release memory to the kernel than the stock glibc allocator.
Tested on jemalloc 3.6.0 (self-built) and libtcmalloc-minimal 2.0-2
(Debian package) on x86_64-linux

* ext/socket/init.c (rsock_connect): refactor for blocking
(wait_connectable): clear error before wait
[Bug #9356]
We no longer use non-blocking sockets to emulate blocking behavior,
so eliminate error-prone and confusing platform-dependent code.
According to POSIX, connect() only needs to be called once in the
face of EINTR, so do not loop on it.
Before waiting on connect, drop any pending errors, since
rb_wait_for_single_fd may not clear the existing error
properly.

* ext/pathname/lib/pathname.rb (SAME_PATHS):
Pathname#relative_path_from uses String#casecmp to compare strings
on case-insensitive filesystem platforms (e.g., Windows). This can
return nil for strings with different encodings, and the code
previously assumed that it always returned a Fixnum. [Fix GH-713]

[ccan 7ec5b8e06b2fd5fa98b1fcde1158c286d2d429d8] (David Gibson)
It's quite common to have a pointer which could be either a pointer to a
structure member, or NULL. This needs special casing with container_of(),
or it will convert NULL into something strange.
This patch adds container_of_or_null(), which will return NULL if passed
(an appropriately typed) NULL, or the containining structure as
container_of() otherwise.

If we needed a volatile there, every other alloc function would need it.
There is nothing special I can see about thread_alloc which would
justify it.

* proc.c (rb_proc_alloc): inline and move to vm.c

[ruby-core:64994]
* vm.c (rb_proc_alloc): new inline function
(rb_vm_make_proc): call rb_proc_alloc
* vm_core.h: remove rb_proc_alloc, add rb_proc_wrap
* benchmark/bm_vm2_newlambda.rb: short test to show difference
First we allocate and populate an rb_proc_t struct inline to avoid
unnecessary zeroing of the large struct. Inlining speeds up callers as
this takes many parameters to ensure correctness. We then call the new
rb_proc_wrap function to create the object.
rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but
we only use it inside rb_proc_alloc. We must call this before
the compiler may clobber VALUE parameters passed to rb_proc_alloc.
