Sorry about the priority and I will keep that in mind for further submissions
;)

For me to reproduce this problem is easy its happens always with trunk version
of Mono (Might be revision 148995 that caused this).  The exact problem is that
xsp reads from mono the following:

1. Packet size + protocol version (5 bytes in total) (Goes good)
2. Fills the buffer for the rest.  But (here comes the issue)

The read from mod_mono is good but as it is putting it into the byte array of
MemoryStream directly.  When MemoryStream.SetLength is called it clears the
first (5 bytes) from the array.

This causes GetString() method to throw "Abnormal string size" exception.

I know this is an issue with MemoryStream.cs but I also think ModMonoRequest
should not assume how MemoryStream handles it internal buffer.

Another note:
My patch is not perfect as it should reuse the buffer that is used for reading
from the buffer. So I am attaching another patch to fix that (Includes prev
patch).
