fs.open/fs.openSync in node v0.10.x can not propagate ENFILE errors

[rmg]

• Version: v0.10.x
• Platform: posix
• Subsystem: fs, deps

As described in libuv/libuv#899, libuv v0.10.x does not translate/propagate ENFILE errors, so node reports it as an UNKNOWN error code. Note that EMFILE occurs far more commonly, and this likely affects more tests (trying to trigger EMFILE/ENFILE to test errr handling) than actual applications.

I don't expect this issue to be fixed. This is mainly for people to find in search results.

Does this classify as something that really needs to be fixed in a maintenance release?

@nodejs/lts: Given that v0.10 is coming up to EOL and it is unlikely that we will be cutting a new v0.10 release, I recommend closing this.
