Description Egor Ushakov 2010-11-11 10:52:42 UTC 
sometimes pty processes remain running after application was closed and consume 100% cpu
Comment 1 Nikolay Molchanov 2010-11-11 15:31:57 UTC 
Here is the stack trace of one of two "pty" processes that were running
infinite loop on my system:

% pstack 27871
27871: /net/.../solstudio12.2-intel-S2/netbeans/ide/bin/nativeexecution/SunOS-x86_64/pty
 fef2a5b5 __pollsys (8046f10, 2, 0, 0) + 15
 feecf672 poll     (8046f10, 2, ffffffff, 0) + 52
 08050fee loop     (3, 8047380, feffb818, 80473a4) + 72
 080514be main     (2, 80473f8, 8047400) + f2
 08050ddc _start   (2, 8047530, 80475b6, 0, 80475be, 8047603) + 80

Please, let me know if you need more details.

Overall I like this feature very much! I'll use it very often, so, please,
fix this bug.

Thanks.
Nik
