Error: ENXIO: no such device or address, open '/dev/stdin' about pipe-args

[gpestana]

readFileSync uses stat(2) to calculate the size of files to read. Since it is impossible to know beforehand the size of /dev/stdin, the exception with code ENXIO was thrown. Perhaps also the fact that stdin fd in node is abstracted as socket and not a pipe anymore. This makes it tricky to write sync code for it.
The solution was to use readSync and read through the contents of /dev/stdin, explicitly giving the buffer offsets, etc..
