Hi,
I experience strange behaviour with libevent on Solaris in combination with
pipes.
Start the following program and then kill its child. The parent goes in an
endless loop instead of exiting.
When using socketpair() instead of pipe() everything works as expected.
Setting EVENT_NOEVPORT=y also makes it work.
Im using libevent-1.4.9-stable on Solaris 5.10
