I think what's missing is a call to [handle closeFile]. From the
NSFileHandle docs:
Sending closeFile to a file handle does not cause its deallocation.
Deallocation of a file handle deletes its descriptor and closes the
represented file or channel only if the handle was created

I don't think so; more likely the NSPipe instances weren't being
released at the end of each loop iteration.
FILE *rtn = popen([@"
I guess it may be a bug.
I achieved more or less the same thing bypassing NSTask and NSPipe
and now have no issues with resource management.

there probably are more efficient ways of doing this but effi

Sre you sure the NSPipes are being dealloc'd? Are you sure you have sent
release/autorelease enough times? NSTask probably retains the NSPipes. Are
you reusing the same NSTask? If
so I see at least one other thread on this topic but no real solution.

works great until I run out out NSPipes - about 248 iterati
