You can/will have problems with this approach under Windows as well.
You do not close the stream, thus not closing the connection. By
default you have only 2 web connections per host, and the next
connections are queued. There may be a bug/problem with the mono
implementation, which does not autoclose the connections in the
timeout period though.

Windows is a 32-bit extension to a 16-bit graphical shell for an 8-bit
operating system originally coded for a 4-bit microprocessor by a
2-bit company that can't stand 1 bit of competition.
