Actually yes: sim machine in the mainline linux kernel has 20 second
polling loop
in its keyboard driver. This issue didn't show up in early
target-xtensa versions
because of bug in clock counter implementation and I must have forgotten to send
an updated kernel after I've fixed it.

Non-semihosting kernels behave more politely.
Looks like it's time for me to update testing kernels/rootfs.
