Our current automation framework builton muliconfig+multi+freestyle is showing up limitations due to executor starvation.(we need our tests to run on multiple windows versions and Ubuntu,RHEL,CentOS,OpenSuse)
We are planning to overhaul it with a label based mechanism using matrix project plugin and get rid of multijobs as much as possible, ( we have multiple restarts in between), so that we get a real time matrix representation of tests.
While evaluating the same we ran into workflow plugin, so wanted to understand few things with regards to workflow plugin, please help
1) Does it provide real time update of tests like the way label based mechanism of blinking dots, we don't want users to do a text find in console output,

2) If there is any error in the groovy script written, does it bring down jenkins server?
3) stupid question , but Does workflow plugin limit itself to 64 bit OS's in anyway? We want support for both 32 and 64 bit OS's
