[Libreoffice] Questions about Timers

Hello,

In the easy hacks, could it be possible to have more information on what 
to do with timers ?
For example :
- what's a "leaked timer", is it the same as "permanent timer" that i 
read on this http://qa.openoffice.org/issues/show_bug.cgi?id=106485 ?
- how to find a leaked timer ?
- how to correct them ? (must we delete them or change them ?)

For example, the timer mpOnlineSpellingTimer that we can find in these 
files :
impress/sd/inc/drawdoc.hxx
impress/sd/source/core/drawdoc4.cxx
impress/sd/source/core/drawdoc.cxx

Is this timer ok ? Is there something we can improve/optimize in it ?

Julien.

PS : in the easy hack, "for RTL_CONSTASCII_USTRINGPARAM macro", wouldn't 
it be better to change the "grep" in "fgrep" in order to make the 
searching faster ?
