The only thread I found about that is here:
http://marc.info/?l=php-internals&m=121442930703916&w=2

I've seen one bug marked as wont fix for this reason. I've searched for
"ticks" and looked at the last few pages of bugs, many was really bogus,
or documentation issues. Some was related to register_tick_function()
and are fixed. I seen nothing really bad or related to the engine.

The ZTS issue looks fixable, this is a crash when using 
register_tick_function() due to the list of functions not being initialized
in the threads.
