[Mono-dev] r135520 change to driver.cs causes "Too many open files" on MacOSX for projects with lots of embedded resources

[Tom Philpot]

            We have a .csproj file with 3000 + embedded resources.  With the
current version of driver.cs (r135520 and later) on Mac OS X, we¹re getting
the following error.
         
Unhandled Exception: System.IO.IOException: Too many open files
           at System.IO.FileStream..ctor (System.String path, FileMode mode,
         FileAccess access, FileShare share, Int32 bufferSize, Boolean
         anonymous, FileOptions options) [0x00000]
           at System.IO.FileStream..ctor (System.String path, FileMode mode,
         FileAccess access, FileShare share, Int32 bufferSize, Boolean

           at System.IO.FileStream..ctor (System.String path, FileMode mode,
         FileAccess access) [0x00000]

         Build complete -- 1 error, 0 warnings

Once I reverted the change from r135520 in driver.cs things started working
again.

Can someone please revert this change until we find a better work around
that doesn¹t break this on Mac OS X? The soft ulimit on num of open files is
256, the hard limit is 1024 by default on Mac OS X.

Thanks.

Tom
