	I'm guessing this has to do with the fact that, "because we're single
threaded (userspace threading), the server process is blocked until all
the data has hit the disk." (this from a recent e-mail from Jan -- the
details are on this page:
http://coda.wikidev.net/Why_to_avoid_a_client/server_combination )

	I'm guessing (and I expect I'll be corrected if I'm wrong) that the
server is busy with the big file and so the other clients are unable to
get a decent response time.  Being write-disconnected is often more
efficient anyway as write operations for multiple files are batched
instead of being done one at a time.

	Generally speaking, coda seems to have issues with very large files,
directories with large numbers of files, and programs that keep files
open for writing on coda.
