call-interactively is in callint.c (around line 235). It calls
temporarily_switch_to_single_kboard (keyboard.c:965) which sets single_kboard
to 1.
read_char (keyboard.c:2260) checks single_kboard in many places.
In ths case it is line 2785, if input from another keyboard arrives it just
jumps back to wrong_kboard: and keeps reading input, thus not exiting until
input arrives from the correct keyboard.
That is about all I know. Just not calling temporarily_switch_to_single_kboard
may solve this, but may have other side effects.
