#3055: Master-side SVN steps use much shorter timeout when removing a working copy
-------------------+-----------------------

Priority:  major   |  Milestone:  undecided

-------------------+-----------------------
 When a working copy is bogus or was locked, the SVN steps attempt to
 remove the working copy. However, the "rm -rf" command that they use has a
 much shorter timeout (120 seconds) than the SVN operations. With huge SVN
 repositories such as !WebKit's, deleting the working copy can easily take
 more than 120 seconds. This results several builds in a row failing until
 the sequence of attempted removals eventually removes the entirety of the
 working copy.

 {{{
 svn --version
  in dir …/build/OpenSource (timeout 1200 secs)

 rm -rf …/build/OpenSource
  in dir … (timeout 120 secs)
 }}}
