2011-04-03	timer threads should sleep and stay asleep... a long time	Rich Felker	1	-1/+1

2011-04-03	revert to deleting kernel-level timer from cancellation handler	Rich Felker	1	-0/+8
	this is necessary in order to avoid breaking timer_getoverrun in the last run of the timer event handler, if it has not yet finished.
2011-04-03	simplify calling of timer signal handler	Rich Felker	1	-3/+1

2011-03-30	avoid all malloc/free in timer creation/destruction	Rich Felker	1	-20/+4
	instead of allocating a userspace structure for signal-based timers, simply use the kernel timer id. we use the fact that thread pointers will always be zero in the low bit (actually more) to encode integer timerid values as pointers. also, this change ensures that the timer_destroy syscall has completed before the library timer_destroy function returns, in case it matters.
2011-03-30	optimize timer creation and possibly protect against some minor races	Rich Felker	1	-14/+19
	the major idea of this patch is not to depend on having the timer pointer delivered to the signal handler, and instead use the thread pointer to get the callback function address and argument. this way, the parent thread can make the timer_create syscall while the child thread is starting, and it should never have to block waiting for the barrier.
2011-03-29	reorder timer initialization so that timer_create does not depend on free	Rich Felker	1	-8/+16
	this allows small programs which only create times, but never delete them, to use simple_malloc instead of the full malloc.
2011-03-29	implement POSIX timers	Rich Felker	1	-0/+110
	this implementation is superior to the glibc/nptl implementation, in that it gives true realtime behavior. there is no risk of timer expiration events being lost due to failed thread creation or failed malloc, because the thread is created as time creation time, and reused until the timer is deleted.
