           Summary: IDLParser.pm exhausts system resources with open2
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org

When building WebCore, IDL files are parsed and binding files are generated
using the code in WebCore/bindings/scripts. Specifically, IDLParser.pm in this
folder uses the open2 call to invoke a preprocessor on the IDL file. If
multiple IDL files are parsed in a tight loop, the code dies after 64 IDL files
because it exhausts the process IDs available. The error message that it dies
with is "Can't spawn-NOWAIT: resource temporarily unavailable".
