Works fine again.

FWIW, I can't reproduce but this has something to do with my efforts 
to change all stream reading to fread().  My goal: I was playing 
around with the COMPRESS IMAP extension - and reading data in from the 
stream using fgets() is not possible (since it is not clear from the 
RFC whether the line breaks are also compressed or not).  Regardless, 
it is a moot point for now since the only practical way of doing 
stream compressions (using PHP filters) can't be done due to the 
overall lousiness of the PHP compression filters - there is no way to 
indicate that you want the output buffer to be flushed.



Long winded way of explaining that I reverted back to the fgets() for 
most commands.  This should fix things - although I have 
moved/consolidated the code a bit so this is not a straight revert.  A 
confirmation that this fixes would be great.

When using previews in the mailbox views, I see 10sec sleeps while 
fetching the individual body peeks:



C (1238491479,6769): 27 UID FETCH 201049 (BODY.PEEK[1])

S (1238491479,7034): * 75 FETCH (UID 201049 BODY[1] {848}

S (1238491489,7071): Hello Jan,



I hope you are doing well and busy improving your software.
