Now, this may not be related to issue you're discussing, but some time ago I 
told Thomas about some temporary delays/lockdown in socket select function 
when attempting to read some emails using IMAP (gmail). Reproducible in this 
sense that killing kmail and trying to read the same email again happened to 
cause the same lockdown again (until it unlocked after some time).

Anyway, it happens only for some signed messages and only sporadically, 
backtrace shows that gpgme (or its C++ bridge) is guilty:

This is 4.4 branch, gpgme-1.2.0, do you think it's related to sending delays?
