Description

This branch fixes several bugs in broctl:

1) on Linux, the broctl "top" command output sometimes shows wrong values for memory statistics,
2) there is a race condition when the "sendmail" option is an empty string,
3) there is a deadlock when broctl runs a local command that produces a sufficiently large amount of output,
4) the shell scripts used by broctl are not as portable as they could be (specifically, some commands, such as sed, do not support the same options on all implementations)
