The file system code should not be calling into NET_* functions. The 
changes to net_util_* will also need cleanup. Otherwise I think you've 
got all the places in the networking / NIO APIs, at least on Linux. 
There are others on macOS, Solaris, ... of course.

That said,  I assume we have many more places in the JDK that have file 
descriptors to open files and other resources. If we really want to 
support the case of someone calling fork/exec from JNI code then it will 
likely need work in several other areas.
