### [Tue Apr 9 13:40:46 JST 2024 : pho]
###
### With "smart scheduler" enabled, Xserver sets up an itimer to
### periodically receive SIGALRM from the kernel while the server is doing
### a socket I/O and processing commands from X clients. When the signal
### arrives while Xserver is in pixman_composite_src_8888_8888_asm_neon()
### or any similar functions from libpixman, the process fails to return
### from the signal handler and exits with status code 22 (EINVAL) due to
### kern/58149. These functions misalign SP while doing some SIMD stuff,
### thereby trigger the kernel bug.
###
### Disabling itimer can avoid the problem but there might be a performance
### regression.
