QUESTION: apr_poll / pipe / win32

[C K Tan]

Hi, In APR 1.1.0, I am using the apr_poll function to wait (blocking) 
on a bunch of sockets in thread A. At some point, thread B needs to 
make thread A exit the apr_poll function even though none of the 
sockets in the pollset is signaled. What's the best way to do it?

I tried adding a pipe to the pollset in A, and have B send a byte to 
make it readable. This works well on unix, but does not work in 
windows. It seems that waiting on pipe is not implemented for windows.

Any suggestions?
Thanks,
