If Gtk objects get updated from other threads than the main thread GTK
can get confused. This is a regression of bcadf64031ee0520212aa8f092f5ac14122cd924.

Rewrites window title according to config option "rewrite".
"rewrite" is an object where keys are regular expressions and values are
rewrite rules if the expression matches. Rules may contain references to
captures of the expression. Regex and replacement follow ECMA-script
rules. If no regex matches, the title is left unchanged.
example:
"sway/window": {
"rewrite": {
"(.*) - Mozilla Firefox": " $1",
"(.*) - zsh": " $1",
}
}
Ipc destructor closes socket and thus wakes up SleeperThread which was
waiting for socket data in Ipc::handleEvent.
Ipc::handleEvent then proceeds with sending signal to already destroyed
object, causing heap-use-after-free Address Sanitizer error.
