35	Rewrite timers	dmik	dmik	"There is a known limitation in PM on the global number of timers that can coexist simultaneously across all processes. On my system, this number is just 28 timers but it probably depends on other system resources and changes from system to system.

When the number of timers has reached its maximum, applications that don't properly handle timer creation errors may hang or crash or just refuse to work if they do handle these errors in a a nice way.

Qt may use quite a lot of timers (several of them are constantly used during the whole application lifetime for things like the blinking cursor and tool-tips). This affects existing applications as described above. See http://svn.netlabs.org/qtapps/ticket/8 for more details about such applications.

The possible way to fix this limitation is to implement our own timer service in Qt which will be independent from system PM timers."	enhancement	new	normal	qt-os2-3.3.1-rc07	kernel		normal		timers
