Timing problems when starting with VBoxHeadless

[cboese]

When trying to start multiple VMs from a script with VBoxHeadless, for every VM I want to start I get the error

ERROR: 0 bytes read from child process 
[!] FAILED calling virtualBox->OpenSession (session, id) at line 669! 
[!] Primary RC  = NS_ERROR_ABORT (0x80004004) - Operation aborted 
[!] Full error info present: false, basic error info present: false

When waiting for a second with sleep 1 this does not happen end everything works fine. I suspect other issues related to this, e.g. ​http://www.virtualbox.org/ticket/2530. You should mention in the documentation, to try the sleep.

I will try VBox 2.1 and report back if the problem still exists.

Host is Ubuntu Hardy (64bit), Guest is Windows XP SP2 (32bit)
