User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 ( .NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.9) Gecko/20100915 Thunderbird/3.1.4

Sending large email over slow connections results in 100% CPU utilization.

Reproducible: Always

Steps to Reproduce:
1. Create a large mail (say 5MB)
2. Connect over a slow connection (64 kbps or so)
3. Send the mail
Actual Results:  
Thunderbird uses 100% CPU while sending the mail.

Expected Results:  
It shouldn't use 100% CPU.

This has been a problem since Thunderbird 2, maybe earlier. Interestingly, it only happens when sending mail. Receiving mail does not use 100% CPU even for huge mail attachments.
