+actually, the issue is not in MonoIO.Seek -- its in io-layer.c's 
+because of the locking sematics in file_write, it seeks on the named 
+pipe fd and fails, thus erroring out on any writes to the fd.
+it doesnt use pipe_write because this is not a pipe fd created with 
+the syscall pipe() via CreatePipe() in io-layer.c. this is a named 
+pipe on the filesystem (an unseekable file).
