In other Unix-ish systems I've used, there are programs called, variously, truss, trace, libtrace, etc. that allow 
attachment to a running process and report on all system and/or library calls.  I haven't found any program like this in
 our QNX environment.  Anybody know whether anything like this is available?  How about any utility that would help 
track down memory leaks?  Any help appreciated.
