it will still crop up if folks run things on older kernels. The
runtime for Go has been issuing SIGURG for preempted goroutines since
~2020.

ext4: allow readdir()'s of large empty directories to be interrupted
Could the same behavior happen for readdir, or is only readdirplus affected?
Should be the same, it calls fuse_emit(), which calls into the filldir
functions in fs/readdir.c.
A way out might be a cached readdir (FOPEN_CACHE_DIR) as the entries do
not get lost.
