Timers: setInterval and setTimeout

[Shripad K]

Hello all,

I'm looking for the right way to implement Javascript-like 
setInterval and setTimeout in D.

I don't want to use multiple threads + sleep as an 
implementation. It needs to be single threaded. I was thinking 
along the lines of creating a timer using ualarm/settimer and 
listening to SIGALARM. I want it to be efficient as i'll be using 
it for timing out HTTP requests.

Can someone guide me in the right direction?

Thanks for any help,
Shripad K.
