Title:
  maliit-server has a memory leak

Status in Ubuntu Keyboard:
  Confirmed
Status in “maliit-framework” package in Ubuntu:
  New

Bug description:
  I've tracked memory utilisation of maliit-server over a 12 hour period
  and can see that the heap is growing at about 1700 bytes a second.
  One can see this by strac'ing the process and seeing glib's malloc
  performing 4K mprotects every ~2.4 seconds and the occasional 1MB
  mmap2 to anonymous memory (aka heap) every 600-620 seconds.

  [pid  2708] 12:48:57 mprotect(0xa01fa000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:48:59 mprotect(0xa01fb000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:49:02 mprotect(0xa01fc000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:49:04 mprotect(0xa01fd000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:49:07 mprotect(0xa01fe000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:49:09 mprotect(0xa01ff000, 4096, PROT_READ|PROT_WRITE) = 0
  [pid  2708] 12:49:11 mmap2(0xa0200000, 1048576, PROT_NONE, MAP_PRIVATE|MAP_ANONY
  MOUS|MAP_NORESERVE, -1, 0) = 0xa0200000
  [pid  2708] 12:49:11 mprotect(0xa0200000, 135168, PROT_READ|PROT_WRITE) = 0

  Over a period of 1 day this will leak 140MB.
