Log:
  Bug 212038 - svn commit: r304321 broken bhyve zvol VM bhyveload hang 100% WCPU
  
  As the support for large blocks was enabled in loader zfs code, the
  heap in userboot was left not changed, resulting with failure of detecting
  and accessing zfs pools for bhyve virtual machines.
  
  This fix does set the heap to use same amount of memory as the zfsloader
  is using. To make it possible to test and verify loader functions, bhyve
  is providing very useful option, but it also means, we like to keep feature
  parity with [zfs]loader as close as possible.
