Detailed Description

fork output stream class

when data is written to it, it writes it to several other streambufs error handling is as follows:

• if writting to a streambuf returns an error, that streambuf is removed from the internal list and no more data is written to it
• when there is no streambuf left to write to eof is returned

Note

doesn't catch any exceptions, so let's the io library decide if they should be propagated
