This appears to be causing the BSD bots to lock up when looking at the core
dumps I've managed to get. Dropping the
FileDesc
structure triggers theArc
it's contained in to get cleaned up, invoking free(). This instead just closes
the file descriptor (the arc itself is never cleaned up).
I'm still not entirely sure why this is a problem because the pthreads runtime
should register hooks for fork() to prevent this sort of deadlock, but perhaps
that's only done on linux?
