ibus-daemon high memory usage

[Daniel Gnoutcheff]

After surfing the web in firefox for a while, I observed that ibus-daemon was occupying a surprisingly large amount of memory (smem reports its unique set size [USS] as 107 MiB). This is much higher than the usage observed shortly after login (about 1.3 MiB USS).

Not sure yet if there's anything in particular needed to trigger this.

I'm seeing ibus use over 600MB after just a couple of months of uptime:

Here, ibus-daemon is taking 577 MiB:

$ ps -C ibus-daemon -o %cpu,%mem,vsz,rss,time,cmd
%CPU %MEM VSZ RSS TIME CMD
 0.0 14.8 956332 591468 00:18:15 /usr/bin/ibus-daemon --daemonize ...

Ubuntu 16.04.2 LTS. Uptime is 19 days.

With 91 days uptime, ibus-daemon I get:

ps -C ibus-daemon -o %cpu,%mem,vsz,rss,time,cmd
