TCP connection is not released

[elasticondo]

When calling

dockerize -wait tcp://sut:10000 <cmd>

dockerize will not release the TPC connection until the <cmd> has finished. This is problematic if the <cmd> requires the TCP connection.

Is this intentional because I do not see the connection being closed within the source code (I am not proficient with go at all).

dockerize/main.go

Line 174 in 9ce2e80

if conn != nil {

If this is intentional, how to circumvent that?
