Still a problem with 1.1.3rc. I've got some truss output (attached)
which shows some differences depending on whether I wait a few seconds
between FETCHes. The sequence of events is

(remove .imap/test.gz directory)

LOGIN ...
SELECT test.gz

(start truss on imap process)

FETCH 1:167 FULL
FETCH 167 BODY[]
FETCH 37 BODY[]
FETCH 123 BODY[]

With a pause it works; without, the FETCH 37 bombs out.

Any idea what's going wrong?

Best Wishes,
Chris
