Here's the doc comment from the commit:
For one example of why this is handy, consider the case of building musl libc.
We keep a lock open for each of the object files in the form of a file descriptor
until they are finally put into an archive file. This is to allow a zig-cache
garbage collector to run concurrently to zig processes, and to allow multiple
zig processes to run concurrently with each other, without clobbering each other.
This code is disabled until #6361 is implemented (getrlimit/setrlimit
are not yet added to the standard library).
This implementation tries to do the right thing (TM) by treating the
sign as part of the number itself, therefore the alignment parameter
applies to both the sign and the digits.
In other words the format string `{:>4}` with -1 as input will not
output `- 1` but ` -1`.
And let's default to right alignment for everything as that's what users
want, especially when printing numbers. Many implementations use
different defaults for numeric vs non-numeric types, let's strive for a
consistent behaviour here.
This brings io_uring helper methods to Zig for kernels >= 5.4.
We follow liburing's design decisions so that anyone who is comfortable with
liburing (https://unixism.net/loti/ref-liburing/index.html) will feel at home.
Thanks to @daurnimator for the first draft.

* caching system: use 16 bytes siphash final(), there was a bug in the
std lib that wasn't catching undefined values for 18 bytes. fixed in
master branch.
* fix caching system unit test logic to not cause error.TextBusy on windows
* port the logic from stage1 for building glibc shared objects
* add is_native_os to the base cache hash
* fix incorrectly freeing crt_files key (which is always a reference to
global static constant data)
* fix 2 use-after-free in loading glibc metadata
* fix memory leak in buildCRTFile (errdefer instead of defer on arena)
This reverts commit 40cb712d13aff4bfe83256858ad6b18d82e70211.
Thanks to Ava & Luna of Lavatech, we don't need to resort to this, they
have graciously given zig a SourceHut instance to use that gives us 8GB
RAM.
Before merging, do this for every item in the file:
* solve the issue, or
* convert the task to a github issue and update the comment
to link to the issue (and remove "TODO" text from the comment).
Then delete the file.
