[Dovecot] Thunderbird body search and multiple imap process

[Oliver Schulze L.]

Hi,
I'm having an issue with dovecot and Thunderbird and it is reproducible 
all the time.
You do many body search from TB and you end up with multiple imap processess
consuming all the CPU and with linux load 20+

Setup:
- Centos 4.5
- Thunderbird 2.0.0.5
- Dovecot 1.0-7_53.rc29 and 1.0.1-1_58.el4

How to reproduce:
- have an imap account in Thunderbird with 12000+ emails
- user maildir in dovecot
- do a: ps auwx|grep user1|grep imap|wc -l
- in the main window of TB, in the sarch box select "Entire Message"
- search one random word and wait 30 seconds
- search another random word and wait 30 seconds
- search another random word and wait 30 seconds
- search another random word and wait 30 seconds
- do another: ps auwx|grep user1|grep imap|wc -l
- watch that the user1 have now more imap process
- watch the linux load, it just rocketed from 1 to 20
- killall -9 imap
- watch the linux load return to 1

I'm thinking its TB fault, anyone has seen this issue too?

Thanks
Oliver
