Re: [Bordeaux-threads-devel] CONDITION-WAIT with timeout

Hi

Are there any plans to support a timeout for bordeaux-threads:condition-wait? The implementations I'm aware of support this threading primitive:

• ABCL could presumably do it since Java Object.wait can take a timeout
• SBCL supports it using sb-thread:condition-wait with keyword :timeout [1]
• anything with POSIX threads underneath could use pthread_cond_timedwait

The main variation seems to be between those implementations that use an absolute time and those that use a relative time (how long to wait in milliseconds for example).

Since I think I need this feature I might try to write a patch to do this for ABCL and SBCL if there is nothing already in the works (unless there is some technical problem I'm not seeing?)

I'd like to, but what do we do for those implementations that don't support timeouts ?
