<div class="ContentPasted0">The preClose() method internally
calls the dup2() system call. If there is a dup2() call on a
file descriptor on a thread while another thread is blocked in
a read/write operation on the same file descriptor, then the
dup2() call is known to hang. Currently, preClose()
experiences a hang because we call dup2() before killing the
reader/writer thread(s).

The JDK has a lot of tests for async close so if dup2 is hanging
then I would expect at least some test failure. Which operating
system (and version) is still happening on? Do you know SO_LINGER
has been enabled?<br>
