Incredibly slow on write

**Describe the bug**
Recently upgraded vim, and I noticed that vim basically froze every time I wrote a file. I opened a typescript file with about 200loc and profiled using this set of commands: https://stackoverflow.com/a/12216578/3269537
To profile I just opened the file and saved it, then closed the file.

Output:
```

notice that maktaba takes ~5s and codefmt takes ~2.5

**To Reproduce**
Minimal vimrc:
```
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'

Plugin 'google/vim-maktaba'
Plugin 'google/vim-codefmt'
Plugin 'google/vim-glaive'

call vundle#end()
call glaive#Install()

" Set up useful defaults for codefmt.
augroup autoformat_settings
autocmd FileType bzl AutoFormatBuffer buildifier
autocmd FileType c,cpp,proto,arduino AutoFormatBuffer clang-format
autocmd FileType dart AutoFormatBuffer dartfmt
autocmd FileType go AutoFormatBuffer gofmt
autocmd FileType gn AutoFormatBuffer gn
autocmd FileType html,css,sass,scss,less,json,vue,javascript,javascriptreact,typescript,typescriptreact AutoFormatBuffer prettier
autocmd FileType java AutoFormatBuffer google-java-format
autocmd FileType python AutoFormatBuffer yapf
autocmd FileType rust AutoFormatBuffer rustfmt
augroup END
Glaive codefmt plugin[mappings]

autocmd BufWritePre * FormatCode
```

**Expected behavior**
Previously this was not nearly this slow. I was expecting a non-noticeable latency on save.

**OS (version)**
Ubuntu 20.04.3 LTS

**Additional context**
vim version: VIM - Vi IMproved 9.0 (2022 Jun 28, compiled May 10 2022 08:40:37)

Tái hiện độ trễ bằng vimrc tối thiểu và quy trình profiling khi lưu/đóng được mô tả trong issue. Bắt đầu bằng cách lần theo FormatCode, codefmt#FormatBuffer() và maktaba#syscall#Call(); công việc được xem là hoàn tất khi việc lưu tệp TypeScript 200 dòng không còn gây ra độ trễ vài giây đã được báo cáo.
