From comment 12 bug 175300:
> We have a report of "Connect" for a Linux systemType taking 5 - 10 minutes (!)
> and completely blocking Eclipse during that time.
> 
> Attached thread dump shows that the problem is calling into
>         LinuxProcessHelper.populateUsernames(LinuxProcessHelper.java:117)
> from
>         LinuxShellProcessService.initService(LinuxShellProcessService.java:194)
> which is called on the main Thread.
> 
> The Javadocs of IService#initService() say:
>    "This method may be long-running, but is not yet expected to open a
>     connection to a particular remote system.
>    "
> 
> So I see two problems here: 
> (1) if initService() may be long-running, why is it called on the main 
>     Thread? This looks like an inconsistency in RSE Core. Not sure if we
>     can change it though, we might have to update the Javadocs instead
>     ("Specification update").
> (2) if initService() is not yet expected to open a connection, why does it
>     initialize user names already?
> I think that the populateUsernames() must be deferred to when it is really
> needed.
