           Summary: make for large projects halts main application UI
           Product: kdevelop
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: logic at jrlogic.dyndns.org


Version:           kdevelop-031003 snapshot (using KDE KDE 3.1.4)
Installed from:    Gentoo Packages
Compiler:          gcc-3.2.3 

When building a large project (with sources that take some time to compile), the entire application slows to a crawl. This is on a dual processor system and make is running with -j 1. Selecting "stop" from the build menu has no effect, the build continues to run.

I didn't build kdevelop with a lot of debugging info, but I attached to it with gdb and saw that it was spending a LOT of time parsing output from the make child process. This doesn't seem to account for the total lack of response in the main application, or the failure of the make widget to accept the signal sent by selecting "stop" from the build menu.

As the build progresses, the responsiveness degrades.
