[syslog-ng] 60 second delay when log rotates, can this be avoided?

[Michael Toy]

I have a log which is received over TCP and is being written to a  
local file name which changes (with syslog ng macros) once per hour.

I am also sending that same stream to a program.

When the log rotates, all data seems to stop flowing for exactly 60  
seconds, both to the log file and to program.

Is there any way to change this?
